A chiralplatinum(II) complex with a helical Schiff-base [4]helicene ligand exhibits intense red circularly polarized phosphorescence (CPP) with a glum of 0.010 in the dilute solution state. The intense CPP was caused by a change in the electronic transition character based on the induction of the helical structure.
具有螺旋席夫碱[4]螺旋烯配体的手性铂( II )络合物在稀溶液状态下表现出强红色圆偏振磷光(CPP), g lum为0.010。强烈的CPP是由基于螺旋结构的诱导的电子跃迁特性的变化引起的。
