  酮香豆素：新型三重态敏化剂

  摘要：

  制备了3-酮香豆素的几种衍生物，并显示它们具有有效三重态敏化剂所需的许多光物理标准。这些化合物包括3-芳酰基香豆素（1）和3，3'-羰基双香豆素（2）。1中的芳基是苯基和取代的苯基衍生物或杂环基，例如噻吩基和苯并呋喃基。1和2中香豆素部分上的取代基（如果有）是烷氧基或二烷基氨基。这些化合物的最大吸收在330至450 nm之间，消光系数在10 4至几乎10 5的范围内。，这是对光敏抗蚀剂和光刻中使用的聚合物薄膜进行有效敏化的重要标准。几个导数的单重态-三重态系统间穿越（isc）效率接近统一。但是，在其他情况下，无辐射衰变过程则与isc竞争。衰减过程是在的不对称取代的衍生物特别优势2，但似乎在聚合物基质可以显着抑制。这些化合物的三线态能量的范围从CA。48至60 kcal / mol。这些酮香豆素中的一些显示出磷光光谱，表明存在“冷冻”旋转异构体。
