Transfer news: The use of a simple method allows the various sensitization steps in EuIII‐containing complexes to be deciphered. Incorporation of an increasing number of electron‐withdrawing fluorine atoms on the rigid and electronically tunable phenyl spacer between two tridentate binding units (see picture, red O, dark blue N) affects the quantum yield, intersystem crossing, and energy‐transfer processes
Transfer news : 使用简单的方法可以破译含Eu III的复合物中的各种敏化步骤。在两个三齿结合单元(见图,红色 O,深蓝色 N)之间的刚性和电子可调苯基间隔基上掺入越来越多的吸电子氟原子会影响量子产率、系统间交叉和能量转移过程理性的方式。
