摘　　要：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 ofπ-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.
