The synthesis and characterization of new peripherally tetra-3,5-dimethylpyrazole-1-methoxy substituted metal-free (4), zinc (5), nickel (6), cobalt (7), copper (8) and lead (9) phthalocyanines are described for the first time in this study. The photophysical (fluorescence quantum yields and fluorescence lifetimes) and photochemical (photodegradation and singlet oxygen quantum yields) properties of
新型无环四,3,5-二甲基吡唑-1-甲氧基取代的无金属(4),锌(5),镍(6),钴(7),铜(8)和铅(9)的合成与表征这项研究中首次描述了酞菁。在二甲基亚砜(DMSO)中研究了无金属酞菁(4),锌(5)和铅(9)的光物理性质(荧光量子产率和荧光寿命)和光化学性质(光降解和单态氧量子产率)。镍(6),钴(7)和铜(8)由于过渡金属和酞菁腔中中心金属的顺磁性行为,未对酞菁(6-8)进行评估。还研究了无金属(4),锌(5)和铅(9)酞菁的荧光猝灭行为。这些酞菁类化合物的荧光发射可通过DMSO中的1,4-苯醌有效地猝灭。
