    • A structural measure would be the construction of dendrimers from subunits with different polarities in a sequential fashion, i.e., starting from a non-polar core and continuing through increasingly more polar generations until a highly polar (perhaps even charged) surface is reached. First steps in this direction have already been made: L. Shu, A. D. Schlüter, Macromol. Chem. Phys. 2000, 201, 239-245.

    • It is assumed that despite back-folding processes, probes positioned at certain generations are at an increasingly large distance from the core the higher the generation at which they are attached.

    • In this approach, the formation of pyrene excimers from the dummies has to be avoided. This is achieved by selectively exciting only the fluorescence probes, which is possible by virtue of their red-shifted UV absorption spectra in comparison to those of the dummies.
