Abstract
Zinc 9, 18, 27, 36-tetrakis(p-tolyl)tetrabenzoporphyrin (ZnTTBP) was synthesized, photophysical process was determined by absorption and fluorescence spectra, fluorescence lifetime measurements, and transient absorption measurements. ZnTTBP has absorption of Q-band at 620nm, Soret at 420nm, and the fluorescence emission and T-T absorption were observed at 630nm and 480nm, respectively. Sensitization to a photo acid generator (PAG) does not occur from one-photon excited S1 or T1 states, while irradiation of the mixture of ZnTTBP and the PAG by 635nm and 490nm light changes the absorption spectrum due to the generation of ZnTTBP cation. This result suggests electron transfer from ZnTTBP to PAG occurred. Isobutyl vinyl ether was polymerized by the acid generated via ZnTTBP sensitization.
