A variety of N-fused porphyrin derivatives were synthesized by the ring-fusion strategy and their photophysical properties were investigated. Observed near infrared fluorescence would be derived from excited-state intramolecular proton transfer. In addition, larger two-photon absorption cross sections were observed in the N-fused porphyrin derivatives. Meanwhile, double-decker iron(II) complex of N-fused porphyrinato was successfully synthesized, having unique three-dimensional d-Π conjugated system. These results clearly illustrated the effectiveness of ring-fusion strategy in study of near infrared dyes.

采用稠环策略合成了一系列N-稠合卟啉衍生物，并对其物理性质进行了研究。观察到的近红外荧光将来自激发态分子内质子转移。此外，在N-稠合卟啉衍生物中观察到较大的双光子吸收截面。同时，成功合成了N-稠合卟啉合双层铁（II）配合物，具有独特的三维d-Π共轭体系。这些结果充分说明了稠环策略在近红外染料研究中的有效性。
