A synthesis of a novel zinc phthalocyanine with four 3-[(2-diethylamino)ethyl]-7-oxo-4-methylcoumarin dye groups at the non-peripheral positions was performed and characterized. The photophysical and photochemical properties of the peripherally (p) and non-peripherally (np) tetra-3-[(2-diethylamino)ethyl]-7-oxo-4-methylcoumarin substituted zinc (II) phthalocyanines are reported. The effects of the
进行了新型的酞菁锌的合成,该酞菁锌在非外围位置具有四个3-[(2-二乙基氨基)乙基] -7-氧代-4-甲基香豆素染料基团。报道了外围(p)和非外围(np)四-3-[(2-二乙基氨基)乙基] -7-氧代-4-甲基香豆素取代的锌(II)酞菁的光物理和光化学性质。还研究了取代基的位置和聚集对这些配合物的光物理/光化学性质的影响。描述了np-ZnPc的光降解,单线态氧和荧光量子产率以及二甲基亚砜(DMSO)和DMSO和DMSO + Triton-X 100溶液的荧光寿命的一般趋势。对酞菁锌。四取代锌酞菁配合物(np-ZnPc和p-ZnPc)的荧光被有效地猝灭了1,4-苯醌(BQ)。
