Zinc porphyrin dimers and trimers, in which the porphyrins are connected via a ruthenium metal core, exhibit large third-order nonlinear optical absorption coefficients and refractive indices. These properties are a result of the presence of multiple porphyrins, which lead to an extension of the π-conjugated system and the octupolar effect.
锌卟啉二聚体和三聚体中,卟啉通过钌金属核心相连,表现出较大的三阶非线性光学吸收系数和折射率。这些特性是多个卟啉存在的结果,这导致了π共轭体系的扩展和八极效应。
