摘要

Abstract

Circularly polarized light exhibits promising applications in future displays and photonic technologies. Circularly polarized luminescence (CPL) from chiral luminophores is an ideal approach to directly generating circularly polarized light

in which the energy loss induced by the circularly polarized filters can be reduced. Among various chiral luminophores

organic micro-/nano-structures have attracted increasing attention owing to the high quantum efficiency and luminescence dissymmetry factor. Herein

the recent progress of CPL from organic micro-/nano-structures is summarized. Firstly

the design principles of CPL-active organic micro-/nano-structures are expounded from the construction of micro-/nano-structure and the introduction of chirality. Based on these design principles

several typical organic micro-/nano-structures with CPL activity are introduced in detail

including self-assembly of small molecules

self-assembly of π-conjugated polymers

and self-assembly on micro-/nanoscale architectures. Subsequently

we discuss the external stimuli that can regulate CPL performance

including solvents

pH value

metal ions

mechanical force

and temperature. We also summarize the applications of CPL-active materials in organic light-emitting diodes

optical information processing

and chemical and biological sensing. Finally

the current challenges and prospects in this emerging field are presented. It is expected that this review will provide a guide for the design of excellent CPL-active materials.
