| Abstract
| - The fluorescence of polyphenylene dendrimers and the intramolecular energy transfer inpolyphenylene dendrimers containing a perylenediimide core have been investigated in this paper.Polyphenylene dendrimers composed of tens or hundreds of out-of-plane twisted phenyl units exhibitstrong fluorescence, with quantum yields ranging from 0.2 to 0.5 depending on the dendrimer generationand its degree of functionality. The fluorescence of polyphenylene dendrimers can be efficiently quenchedby the incorporated perylenediimide core, and consequently, a predominant emission from the core hasbeen observed, indicating a very efficient intramolecular energy transfer.
