摘要：
The effects of molecular size, conjugation length, and competition with excimer formation on excited state intramolecular proton transfer (ESIPT) in conjugated polymers, in which the intramolecularly hydrogen-bonded moieties reside in the main chain, were examined. A large extent of pi-electron delocalization is found to inhibit the ESIPT process. Excimer formation is found to be competitive with ESIPT in the polymers studied, whereas molecular size does not inhibit ESIPT.
