continuing efforts to develop second generation photodynamic therapeutic agents [1], we synthesized three pentacyclic azine dyes that were designed with the aid of MNDO calculations to absorb visible light having wavelengths longer than 600 nm. Photophysical measurements for the azine dyes 1,4,8,11-tetraethyl-1,2,3,4,8,9,10,11,13-nonahydrodipyrazino[2,3-b:2′, 3′-i] phenazinium acetate, 13, 1,4,8,11-tetraethyl-2
作为开发第二代光动力治疗剂的不断努力的一部分,我们合成了三种五环嗪染料,这些染料是根据MNDO计算设计的,可吸收波长大于600 nm的可见光。嗪染料1,4,8,11-四乙基-1,2,3,4,8,9,10,11,13-nonahydrodipyrazino [2,3- b:2',3'- i ]的光物理测量吩嗪乙酸酯,13,1,4,8,11-四乙基2,3,4,8,9,10,11,12,13八氢-13- methyldipyrazino [2,3- b:-2,3'- i ]碘化碘鎓14和1,4,8,11,13-五乙基-2,3,4,8,9,10,11,12,13-八氢二吡嗪并[2,3- b:2',3 ′ -i ]碘化碘鎓,15相对于三环模型化合物3,7-bis(diethylamino)phenazinium chloride,20和3,7-bis ,其吸收光谱出现35 nm红移,其单线态氧量子产
