Abstract

We have previously shown that diphenylpolyenes incorporating diphenylamino donor substituents form exceptionally stable bipolaronic dications in solution, even at the bis-(diphenylamino)-E-stilbene level, whereas most previously known polyenylic bipolarons were unstable at lengths shorter than the tetraene1. Most recently we have also demonstrated that replacement of one of the diphenylamino substituents in the stilbene substrate with a N-(hydroxyethyl), N-ethylaminophenyl group yields a functionalized polyene that can easily be attached to PMMA as a pendant group, or to 3,5-dihydroxy-benzyl alcohol to form reactive dendrons2. These functionalized materials also form extremely stable bipolarons and are intensely fluorescent. In this presentation we will discuss the formation of G-0 dendrimers incorporating a series of polyenes related to the stilbene structure, and possible photonic applications.
