the complexes (1-4) related to the generation of singlet oxygen (1O2) was studied in detail. The presence of triplet excited state in the complexes was probed from perylene assay. Photo-activated generation of singlet oxygen from the complexes was probed by DPBF assay and the degree of photo-cytotoxicity of the complexes was related to their ability in photo-activated 1O2 generation. Complexes 4 exhibited
四种新的三价氧钒(IV)配合物[VO(L)(B 1-4)](acac),其中L =(E)-2-(2-羟基苄叉亚氨基)-5-胍基戊酸(精氨酸水叉亚基)和B是1H-咪唑-[4,5-f] [1,10]-菲咯啉(B 1)(1),2-苯基-1H-咪唑并[4,5-f] [1,10]菲咯啉(B 2)(2),2-(萘-1-基)-1H-咪唑并[4,5-f] [1,10]菲咯啉(B 3)(3)或1-(吡啶-2-基)-1H合成了咪唑并[4,5-f] [1,10]菲咯啉(B 4)(4),并进行了表征,并在黑暗和可见光(400–700 nm,10 J cm -2)下研究了A549细胞的光细胞毒性。配合物的光化学1 - 4)与单重态氧(产生1 Ò 2)进行了详细研究。从per分析中探查复合物中三重激发态的存在。通过DPBF分析探测了从复合物中光活化产生的单线态氧,并且复合物的光细胞毒性程度与它们在光活化1 O 2产生
