n] platinum was synthesized and its photophysical study revealed that it had a high quantum yield of singlet oxygen generation. As an application study, a stereo-specific synthesis of (+)-deoxoartemisinin was performed. The induced high triplet quantum yield (0.96 ± 0.03) of [5,10,15-triphenyl-20-(4-methoxycarbonylphenyl)-porphyrin] resulted the high singlet oxygen quantum yield of 0.90 ± 0.04. The
合成了一种新型的[5,10,15-三苯基-20-(4-甲氧基羰基苯基)-卟啉]铂光催化剂,其光物理研究表明,它具有高的单线态氧生成量子产率。作为一项应用研究,进行了(+)-脱氧青蒿素的立体特异性合成。诱导的[5,10,15-三苯基-20-(4-甲氧羰基苯基)-卟啉]的高三重态量子产率(0.96±0.03)导致了0.90±0.04的高单重态氧量子产率。将光催化作用与亚甲基蓝(MB)的光催化作用进行了比较,亚甲基蓝通常用作这些类型的有机化合物的立体特异性合成的光催化剂。合成的(+)-脱氧青蒿素的产率与单线态氧量子产率相关。
