The excited state dynamics and two-photon absorption properties of four novel triply linked porphyrin dimers in toluene have been investigated. The fused porphyrin dimers exhibit extremely increased two-photon absorption cross-section values (12,000-15,000 GM) compared with porphyrin monomers owing to much enhanced pi-electron delocalization throughout the porphyrin dimer ring.
研究了四种新型三连接卟啉二聚体在甲苯中的激发态动力学和双光子吸收特性。与卟啉单体相比，稠合卟啉二聚体表现出极大增加的双光子吸收截面值（12,000 - 15,000 GM），这是由于整个卟啉二聚体环中的π电子离域得到了极大增强。
