A series of full-color circularly polarized luminescence (CPL)-active materials are fabricated by judiciously combining multifarious chiral nanoarchitectures with achiral fluorescence dyes. The investigated nanoarchitectures include organic polymer nanofibers, organic-inorganic hybrid nanoflowers, and inorganic nanoflowers. The as-prepared chiral nanoarchitectures all can act as handed-selective fluorescence filters to powerfully transform unpolarized fluorescent light into circularly polarized luminescence. Also notable, no interaction is required between chiral and fluorescent components for achieving CPL emission. The present study provides a convenient and universal approach for preparing full-color CPL materials. Following the strategy, numerous chiroptical materials with CPL performance can be expected due to the abundant chiral matters and achiral fluorophores.
通过巧妙地将多种手性纳米结构与非手性荧光染料相结合,制备了一系列全色圆偏振发光(CPL)活性材料。所研究的纳米结构包括有机聚合物纳米纤维、有机-无机杂化纳米花和无机纳米花。所制备的手性纳米结构都可以作为手性选择性荧光滤光片,将非偏振荧光有效地转化为圆偏振发光。同样值得注意的是,实现CPL发射不需要手性和荧光成分之间的相互作用。本研究为制备全色CPL材料提供了一种简便通用的方法。按照该策略,由于丰富的手性物质和非手性荧光团,有望得到大量具有CPL性能的手性光学材料。
