5-(4-Carboxyphenyl)-10,15,20-tris(phenyl)-porphyrinato chlorido gallium(III) (2) was synthesized and then linked to ethyl ester δ-aminolevulinic acid to form 3. There was no shift in Soret band following conjugation. The fluorescence and singlet oxygen generating behavior of the porphyrins were also investigated. The highest singlet oxygen quantum yield (ΦΔ) obtained was that of 3. Complexes 2 and 3 as well as metal
摘要 合成了 5-(4-Carboxyphenyl)-10,15,20-tris(phenyl)-porphyrinato chloridogallium(III) (2),然后与乙酯 δ-氨基乙酰丙酸连接形成 3。结合后的 Soret 带。还研究了卟啉的荧光和单线态氧产生行为。获得的最高单线态氧量子产率 (ΦΔ) 是 3。配合物 2 和 3 以及不含金属的 5-(4-羧基苯基)-10,15,20-三(苯基)-卟啉对 MCF 没有暗毒性-7个乳腺癌细胞。
