摘要: 含丙基取代的不对称联三吡咯大环化合物及其金属配合物的合成已在前文报道,这些配合物在740~780nm光谱区域内具有强的光吸收。其单重态氧的生成可由它的光敏氧化蒈烯得到约68%高产率的“ene”型产物所证实,同时测定了它们的单重态氧量子产率(φ1O2)及荧光量子产率(φ1)。

Abstract: The synthesis of propyl substituted asymmetrie tripyrrole-Containing macrocycles and their metal complexes are reported.These complexes show strong optical absorptions in the 740~780 nm spectral region and effectively sensitize the production of singlet oxygen as proved by their sensitized photo oxygenation of △3-carene forming good yield of “ene” type products, about 68% and their φ1O2 and φ1 are also determined.

Key words: singlet oxygen, porphyrin-like, tripyrrole, photosensitizer
