最近，共价连接或自组装的卟啉阵列系统因其增强的双光子吸收（TPA）行为而备受关注。在这项研究中，我们研究了各种二面角控制的、直接连接的卟啉二聚体和阵列的TPA特性，以阐明π共轭途径与TPA特性之间的关系。我们已经证明了卟啉组装体中的π共轭（芳香性）和TPA特性之间存在很强的相关性。
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 pi-conjugation pathway and TPA properties. We have demonstrated a strong correlation between pi-conjugation (aromaticity) and TPA properties in porphyrin assemblies.
