Abstract

Two new symmetrical two-photon free-radical photopolymerization initiators, 1,4-bis-{2-[4-(2-pyridin-4-ylvinyl)phenyl]vinyl}-2,5-bisdimethoxybenzene 6 and 1,4-bis-{2-[4-(2-pyridin-4-ylvinyl)phenyl]vinyl}-2,5-bisdodecyloxybenzene 7, were synthesized using an efficient Wittig and Pd-catalyzed Heck coupling methodology. One-photon fluorescence, one-photon fluorescence quantum yields, one-photon fluorescence lifetimes, and two-photon fluorescence have been investigated. Experimental results show that both compounds were good two-photon absorbing chromophores and effective two-photon photopolymerization initiators. Two-photon polymerization microfabrication experiments have been studied and the possible photopolymerization mechanism is discussed.
