The critical question of cyclization during the synthesis of hyperbranched macromolecules has been probed by MALDI-TOF mass spectrometry. Using this versatile technique it was shown that the extent of cyclization depends on a variety of reaction parameters and can predominate in certain systems. This predominance of cyclization can have important implication for the course of the polymerization and the ultimate molecular weight obtained.

Weimer M, Fréchet J, Gitsov I: Importance of active site reactivity and reaction conditions in the preparation of hyperbranched polymers by self condensing vinyl polymerization: highly branched vs. linear poly[4-(chloromethyl)styrene] by metal catalyzed 'living' radical polymerization. J Polym Sci Polym Chem 1998, 36:955-970. In the self condensing polymerization of vinyl monomers, an interesting new field pioneered by Fréchet, the structure of the branched polymer obtained is dramatically influenced by the reaction conditions. For the polymerization of 4-chloromethylstyrene under ATRP conditions the structure goes from essentially linear to hyperbranched by simply increasing the catalyst monomer ratio from 0.01 to 0.30. This has important consequences for other hyperbranched systems.

Macromolecules 1998, 31:6259-6265. In a series of elegant experiments, the direct visualization of single dendrimer molecules was obtained by using advanced TEM procedures. Interestingly, the size of the dendrimers was approximately the same within the same generation and varied in a systematic way with increasing generation number. To first approximation, the dendrimers also appeared spherical, all of these features were consistent with the assumed structure of dendrimers.

J Am Chem Soc 1998, 120:8619-8631. By controlling the size of dendritic side groups attached to a random coil polymer backbone, the overall flexibility of the chain can be readily controlled. Visualization of these nanoscopic structures by a variety of different techniques provides the first comparative study of these novel materials in different environments.

Macromolecules 1998, 31:815-822. By comparing two similar series of dendrimers, which differ only in the nature of the core moiety, the conformational mobility of polyether dendrimers was probed by NMR techniques. Interestingly, these materials were shown to be have a high degree of conformational mobility with the chain end groups having the highest degree of freedom.

One of the most critical findings in this paper is the self assembly of amphiphilic dendrimers at the air-water interface to form stable Langmuir-Blodgett films. This is contrary to our naïve view of these dendrimers which consists of a hydrophobic shell surrounding a hydrophilic interior. This finding adds substantial support to the conclusion that, depending on dendrimer structure, the conformation of these materials can be extremely dynamic.

Newtonian flow behavior of medium and highly concentrated solutions of polyamidoamine (PAMAM) dendrimers in ethylenediamine (EDA) solvent. Macromolecules 1998, 31:4498-4510. The lack of an abrupt change of slope in the zero-shear viscosity vs. molecular weight relationship coupled with Newtonian flow under highly concentrated conditions is fully consistent with the non-entangling model of dendrimers.

In concert with the previous paper, the melt viscosity behavior of a different dendrimer family also shows no critical entanglement molecular weight suggesting that the 3-dimensional highly branched structure of these materials only permits interdigitation of the numerous chain ends.

A similar finding in the study of the melt viscosity of a different family of highly branched macromolecules, arborescent polymers, in which the branching units are polymeric in nature, strongly suggests that this unique property is characteristic of very highly branched structures in general.

J Am Chem Soc 1998, 120:4492-4501. PAMAM dendrimers have been shown to form highly stable and close packed monolayers on gold surfaces. Interestingly the monolayers are still porous and can undergo significant rearrangement on exposure to alkane thiol solutions. The physical and chemical properties of these dendritic monolayers show significant potential for a variety of different applications.

The use of dendrimers as templating agents, in this case of Cu nanoclusters is reported. The discrete size and shape of dendrimers of different generation number can be sued to control the physical properties of the final nanocluster.

The use of dendritic DNA surface layers and mass-selective piezoelectric transducers permits the detection and monitoring of hybridization. This novel type of biosensor relies on the dendritic structure to increase the level and efficiency of hybridization due to the dendrimer's highly branched structure and large number of chain end functional groups.

The unique features of dendritic macromolecules are used to control the phase separation of inorganic thermosetts and thermally decomposable dendrimers. Nanophase separation can be achieved which leads to inorganic thin films with nm-sized pores and dielectric constants less than 2.0.

The exploitation of these is real world sensor applications is discussed.

Chem Mater 1998, 10:286-296. The steric isolation of lanthanide ions at the core of self assembled dendrimer has been shown to lead to a dramatic increase in the luminescence behavior. Interestingly this behavior is generationally dependent and demonstrates that the isolation of the lanthanide ion increases as the size of the dendrimer increases.

Chem Mater 1998, 10:1751-1754. Polyamido dendrimers with oligiothiphene units at the chain ends have been used a 'molecular sponges' to detect volatile organic compounds. It is found that the conductivity of these novel dendrimers increases dramatically with sorption of these molecules leading to potential sensor applications.

Hybrid dendritic linear block copolymers are used to form nanoscopic materials. In this case rigid rod poly(triacetylene) backbones are encases in a surrounding dendritic sheath leading to multi-nanometer long rods, analogous to insulated molecular wires. Interestingly there is no loss of π-electron character even for the case when large dendrimers are attached to the backbone.
