McMurry coupling reactions of new isomeric unsymmetrically substituted triethylbipyrrole dialdehydes. The positional effects of alkyl groups could be manifested through significant alteration in structure of porphycene cores and, as a consequence their photophysical properties, not noticed in β-octaethylporphycene. HOT displays significant fluorescence accompanied by reasonable singlet oxygen generation
两种新的β-六烷基化卟啉,即2,3,7,12,13,17-(HOT)和2,3,6,12,13,16-六乙基卟啉(HIT)首次引入。这些是通过新的异构体不对称取代的三乙基联吡咯二醛的McMurry偶联反应合成的。烷基的位置效应可以通过卟啉核心结构的显着改变来体现,因此,它们的光物理性质在β-八乙基卟啉中没有发现。HOT显示出明显的荧光,并具有合理的单线态氧生成能力。
