摘要
液晶光电材料由于分子结构的各向异性和协同运动特性,在光、电、热、磁等外界刺激下能够发生取向、排列或相态变化,从而表现出宏观形变或光学性质的调控,被广泛应用于显示、光学器件和传感等领域。动态共价键由于具有可逆断裂与重组特性,在光、热、电及pH变化条件下能够实现键交换,赋予材料体系动态响应能力。为了探讨动态共价键在液晶光电材料中的应用,本文重点讨论了动态共价键的动态特性对液晶光电材料刺激性相应行为的影响。将动态共价键引入液晶材料,使材料同时具备液晶分子本征的刺激响应性与动态共价化学的可逆调控特性,该策略能够赋予液晶体系多重刺激响应、形状记忆、自修复及可编程化等功能,为新型智能光电材料的构筑提供了新的研究思路。
To explore the application of dynamic covalent bonds in liquid crystal optoelectronic materials,this work focuses on the influence of their dynamic characteristics on the stimuli-responsive behavior of liquid crystal systems.Benefiting from the molecular anisotropy and cooperative motion,liquid crystal optoelectronic materials can undergo orientation,alignment,or phase transitions under external stimuli such as light,electricity,heat,and magnetic fields,thereby enabling the regulation of macroscopic deformation or optical properties.These features have led to their widespread use in displays,optical devices,and sensors.Dynamic covalent bonds,owing to their reversible cleavage and recombination,can undergo bond exchange under conditions such as light,heat,electricity,or pH changes,endowing the material system with dynamic responsiveness.Incorporating dynamic covalent bonds into liquid crystal materials allows the combination of the intrinsic stimuli-responsiveness of liquid crystal molecules with the reversible regulation of dynamic covalent chemistry.This strategy imparts liquid crystal systems with multiple stimuli-responses,shape memory,self-healing,and programmability,thereby offering new avenues for the design and construction of next-generation intelligent optoelectronic materials.
