Keywords: 稀土Eu(Ⅲ)手性高分子,圆偏振荧光,能量传递,有效调控
Abstract:
手性(R,R)-1,2-环己二胺分别与具有偶数亚甲基烷烃链的S-M-1(4,4'-(butane-1,4-diylbis(oxy))-dibenzaldehyde),S-M-2(4,4'-(octane-1,8-diylbis(oxy))dibenzaldehyde)和S-M-3(4,4'-(dodecane-1,12-diylbis(oxy))-dibenzaldehyde)单元,通过亲核取代-消除反应合成相应的新颖柔性高分子P-1,P-2和P-3.Eu(TTA)3·2H2O分别与P-1,P-2和P-3反应制备相应的柔性稀土Eu(Ⅲ)高分子P-4,P-5和P-6.通过对烷烃主链数目的有效调控,能够有效调控稀土Eu(Ⅲ)的发光效率和圆偏振荧光的不对称因子(glum).实验证明,在一定的激发状态下,稀土高分子仅仅显示Eu(Ⅲ)的红色特征荧光,归于高分子将激发态能量基本传递给配位中心的Eu(Ⅲ)离子.通过对稀土Eu(Ⅲ)高分子的荧光寿命和量子效率表征,P-4,P-5和P-6的发光效率依次降低.P-4与P-5圆偏振荧光(CPL)的最大不对称因子(glum)分别为+0.0873和+0.0115,归属为电偶极跃迁(5D0→7F2);P-6最大不对称因子(glum)为+0.0539,归属为磁偶极跃迁(5D0→7F1).通过烷烃主链数目的差异实现对其CPL的有效调控,调控机理归于高分子折叠所引起稀土Eu(Ⅲ)不对称配位环境的变化.
