Influence of Branching on the Chiral Self-Assembly of Poly(phenylene ethynylene)
In this contribution, we report the synthesis of chiral all-conjugated branched poly(phenylene ethynylenes) with a controlled amount of branching. Subsequently, the self-assembly of these PPEs is studied by means of UV-vis, fluorescence spectroscopy, and DSC and the influence of branching is investigated. Finally, CD-spectroscopy is used to study the influence of branching and self-assembly on the chiral expression of these polymers. (c) 2014 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
