23. •• Polymerization of styrene in spontaneous vesicles formed by mixtures of cationic and anionic surfactants is reported. The vesicle architecture can be controlled by the equilibrium surfactant self-assembly prior to polymerization. The increased shape persistence of the polymer containing vesicles is displayed by the possibility of obtaining atomic force microscopy images of these structures.
24. ••Cryo-electron microscopy investigations show that styrene polymerization within vesicles prepared from dioctadecyldimethylammonium bromide leads to a partial phase separation. The polymer forms a small spherical particle within the bilayer of each vesicle thus leading to a parachute-like morphology.
25. ••Using a crosslinking polymerization of alkyl methacrylates in vesicles leads to homogeneously closed spherical polymer shells. The hollow sphere morphology of these polymers is clearly proved by scanning electron microscopy and confocal microscopy. After isolation from the templating bilayer structure these polymer hollow spheres contract considerably without losing their spherical shape despite their extremely low shell-thickness. The origin of this retention of shape is, as yet, not fully understood and needs to be clarified in the future.

30. •Polystyrene latexes have been coated with thin polyaniline layers to produce electrically conductive core-shell particles. The polyaniline layer has a rather non-uniform and inhomogeneous morphology. Extraction of the polystyrene core leaves the polyaniline shells which display a "broken egg-shell" morphology.
31. •Treatment of gold-ions containing block copolymer micelles with pyrrole leads to the formation of polypyrrole coated gold particles. Depending on the reaction conditions the shape of the gold nanoparticles could be influenced thus leading to spherical, cubic, tetrahedral, octahedral and dendritic morphologies, respectively.
32. ••The ionomeric microdomains of a sulfonated polystyrene-block-poly(ethylene-alt-propylene) diblock copolymer have been used as a matrix for pyrrole polymerization. The polymerization does not disrupt the block copolymer microstructure. Aligned samples displayed anisotropic electric conductivity varying up to two orders of magnitude parallel and normal to the layer planes.

While the size of the CdS particles is directly determined by the length of the polar block, the interparticle distance is controlled by the polystyrene.

48. 40-undecyl - methancrylate as a polymerizable surfactant, continuous pores with sizes in the range from 1-10 nm could be produced. This channel system is believed to be a direct cast of the parental biocontinuous microemulsion whereby the macromonomer obviously prevents structural reorganization during the polymerization because of its low mobility.
49. ••Hydrophilic gels are prepared from acrylamide polymerization in the aqueous lyotropic phases of counterion coupled gemini surfactants. Demixing of the gelling polymer and the surfactant mesophase leads to structures being two orders of magnitude larger than the templating lyotropic phases. Nevertheless, the morphology of the gel is still controlled by the ordered arrays of the surfactant mesophase.

To prevent phase separation during polymerization only a part of the decane has been replaced by hydrophobic alklymethacrylate monomers. The layer structure and its orientation is preserved after extraction of the templating matrix. Macroscopically uniform aligned networks of this type display one-dimensional swelling in water.
51. ••The polyisoprene blocks of the cubic gyroid structure of a polystyrene-block-polyisoprene block copolymer have been selectively degraded by ozonolysis. This leads to the formation of nanometer-sized ordered bicontinuous channels without disturbing the arrangement of the glassy polystyrene. The surface of these nanochannels could be plated with nickel metal thus leading to materials which have a high potential as catalysts.

55. • N-alkylammonium dihydrogenphosphates display thermotropic and lyotropic (in nonaqueous poly(ethylene glycol) solvents) liquid crystalline behavior. The liquid crystalline phases display intriguing surface patterns which are believed to be responsible for similar morphologies observed in lamellar aluminophosphates. Topological defects in the precursor alkylammonium mesophase are proposed to be responsible for these biomemetic forms.
56. • An interesting model helping to rationalize the formation of microporous aluminophosphates is presented. The basic building block according to these considerations is a linear chain aluminophosphate which finally condenses to complex porous layers or open-framework structures.
57. •• The molecular origins of the self-assembly, organization, and phase behavior of alkaline silicate-surfactant liquid crystals are investigated in detail for the first time suing a combination of complementary experimental techniques. The low reactivity of the silicate species under highly alkaline conditions and ambient temperatures allow a decoupling of the surfactant self-assembly process from the kinetics of interfacial polymerization.
58. ••The aggregates of cationic gemini surfactants tend to favor a lower curvature on an anionic mica plane than in solution. These morphologies on mica correlate well with those observed in surfactant-silica mesophases, where electrostatic binding or the headgroups also plays a dominant role. Shape transitions of the interfacial aggregates could be induced be specifically binding counterions, thus eventually providing a method to predict and design specific mesoscopic architectures.

61. ••The lyotropic liquid crystalline phases of amphiphilic block copolymers in water can be used to prepare large crack-free monoliths of mesoporous silica because of an improved elasticity and ductility of the resulting hybrid materials.
62. ••Reduction of platinum salts within the aqueous domains of a hexagonal lyotropic liquid crystalline phase leads to metallic platinum whose nanostructure is a direct cast of the templating phase structure, in other words consists of regular pores in continuous metallic matrix. Because of their high surface area and controlled nanoarchitecture these materials promise great potential for use as catalysis in sensors or batteries.
63. •A versatile route to create mesoporous metal films by electrochemical reduction of platinum salts in the aqueous domains of lyotropic liquid crystalline phases is presented. These films could serve as a new generation of electrode materials.
64. ••The mesostructure of a polyisoprene-block-poly(ethylene oxide) block copolymer has been used as a template for the preparation of organically modified aluminosilicates. Macroscopically uniform aligned samples could be prepared using the solvent-cast technique.
65. ••Ordered hexagonal mesoporous silica structures with uniform pore size up to about 30 nm can be produced using amphiphilic poly(alkylene oxide) triblock copolymers as structure guiding compounds.
66. •• The micellar aggregates of ionic block copolymers can be used as templates for the sol-gel synthesis of mesoporous silica. The resulting silica network is a precise copy of the original self-assembly structure and seems to allow the realization of a rich variety of pore structures.
67. •Highly ordered thin films, plates and fibers can be produced using nonaqueous azeotropic solvents.
68. •• Ordered mesoporous fibers of amorphous or hexagonal mesoporous silica can be realized using bacterial filaments as a substrate for mineralization. Removal of the organic material by calcination leads to hallow mesoporous silica tubules.

72. •An interesting sol-gel based dip-coating method to prepare cantonese thin film on solid substrates is described.
73. •] is used to prepare nanolaminated coatings mimicking nacre. During dip-coating the subsequent self-assembly of a silica-surfactant-monomer micellar species into lyotropic mesophases organizes the organic and inorganic precursors into the nanolaminated form which is subsequently fixed during combined organic-inorganic polymerization.
74. ••Macroscopically uniform orientation by non-condensed surfactant-silica liquid crystals can be obtained by magnetic fields. The orientation is preserved during polymerization thus allowing control over the orientation of the pores within the samples.
75. •Mechanical shear of MCM-41 synthesis gels in the presence of high concentrations of KBr induces macroscopic order which rapidly relaxes after stopping of the shear.
76. ••Microcapillaries served as a substrate for the formation of long oriented silica tubules. An electric field is used to induce electro-osmotic flow of the reaction mixture into the capillaries and to control the rate of polymerization by localized Joule heating. The method allows the formation of oriented microporous channels with on a non-conducting substrate with an arbitrary microscopic pattern.
