Abstract:
Poly(9,9-di-n-octylfluorene-2,7-vinylene)s containing F-BODIPY [PFV-(F-BODIPY)2] and Zn(II)-porphyrin have been prepared by olefin metathesis of the vinyl group in the PFV chain ends followed by subsequent Wittig-type coupling. An introduction of tris(2,5-dialkoxy-1,4-phenylene vinylene) into PFV-(F-BODIPY)2 has also been achieved. The emission properties can be modified by the PFV chain length, chromophore, and the middle segment: PFV-(F-BODIPY)2 exhibits white-light emission with high quantum efficiency.
