metal-free, zinc and indium 1(4),8(11),15(18),22(25)-tetramorpholine (1a, 2a, 3a respectively) and 2(3), 9(10), 16(17),23(24)-tetramorpholine (1b, 2b, 3b respectively) phthalocyanines were synthesized and complexes 2 and 3 were quaternized. The photophysical and photochemical properties were investigated in dimethylsulfoxide. The non-peripherally substituted phthalocyanines generated higher singlet oxygen
在这项研究中,新型无金属锌和铟1(4),8(11),15(18),22(25)-四吗啉(分别为1a,2a,3a)和2(3),9(10 ),合成了16(17),23(24)-四吗啉(分别为1b,2b,3b)酞菁,并将配合物2和3季铵化。在二甲基亚砜中研究了光物理和光化学性质。非外围取代的酞菁产生的单线态氧高于外围取代的酞菁。光动力抗菌化学活性对大肠杆菌,金黄色葡萄球菌和对白色念珠菌进行了评估,其中所有季铵化的Pcs均显示出对微生物的完全消除,对数减少量大于9。尽管中性Pcs的对数减少量小于2,对于白色念珠菌,对2b而言,百分比减少量为68.5%,显示出吗啉类的抗真菌特性。
