In this work, we demonstrate a modified strategy for obtaining a proper dendritic poly(p-phenylenevinylene) (PPV) which shows increasing pi-conjugation length with growing molecular weight. To this end, we employed a simple but novel strategy of adopting 1,2,4-linking (ortho- and para- connecting) AB2 monomer for the dendritically conjugated PPV synthesis, because 1,4-connectivity as well as 1,2-connectivity (lesser extent) contributes to the extension of pi-conjugation lengths. Energy funneling and enhanced fluorescence efficiency were observed in this pi-conjugated hyperbranched polymer. |
