for a series of zinc tetra[6,7]quinoxalino-porphyrazines (6,7-TQP) with peripheral chains connected through the S, O and N heteroatoms as well as through the C―C bond were developed. Photophysical and photochemical properties of 6,7-TQP were compared with tetrapyrazino-porphyrazines (TPP) bearing the same peripheral substituents to disclose the effect of insertion of a benzene ring between the pyrazine
开发了一系列四[6,7]喹喔啉-四氮杂卟啉锌(6,7-TQP)的合成方法,其外围链通过S、O和N杂原子以及C-C键连接。将 6,7-TQP 的光物理和光化学性质与带有相同外围取代基的四吡嗪并四氮杂卟啉 (TPP) 进行比较,以揭示在吡嗪和四氮杂卟啉部分之间插入苯环的影响。还讨论了 6,7-TQP 组中外围杂原子的影响。与 TPP 相比,制备的 6,7-TQP 的主要吸收带(Q 带)发生了强烈的红移和超色移(在吡啶中 λ max = 730-770 nm,c 高达 500000 dm 3 mol ―1 cm ―1 ) . 它们表现出高单线态氧量子产率(Φ Δ = 0.50-0.74)和相对较低的荧光量子产率(Φ F < 0.08)。
