Abstract

Recently, covalently linked or self-assembled porphyrin array systems have attracted much attention for their enhanced two-photon absorption (TPA) behaviors. In this study, we have investigated the TPA properties of various dihedral angle controlled, directly linked porphyrin dimers and arrays to elucidate the relationship between the π-conjugation pathway and TPA properties. We have demonstrated a strong correlation between π-conjugation (aromaticity) and TPA properties in porphyrin assemblies.
