Abstract :
Rigid polyphenylene dendrimers substituted with dyes are suitable substrates for the investigation of interchromophore photophysical processes as they contain discrete numbers of chromophores in well-defined spatial relationships to each other. In this contribution, we provide an overview of the synthesis of such materials and show how a combination of ensemble and single-molecule spectroscopic investigations can be used to elucidate the interchromophore excitation energy transfer processes in them.
