Abstract
Two-photon absorption (2PA) properties of self-assembled porphyrins were investigated. The butadiyne-linked porphyrin array exhibited a 20 times larger 2PA cross section than the meso-meso-linked self-assembled array due to the expansion of pi-conjugation. Higher-order nonlinear absorption was also observed in the former porphyrin.
摘要
研究了自组装卟啉的双光子吸收（2PA）特性。由于π共轭的扩展，与丁二炔连接的卟啉阵列的2PA截面比中-中连接的自组装阵列大20倍。在前者的卟啉中还观察到了高阶非线性吸收。
