摘　　要：从白光凝胶形成的作用方式出发,综述了以氢键作用、π-π堆积作用和金属配位作用等非共价作用来构筑白光凝胶的研究现状,指出,基于非共价键作用构筑的白光凝胶可使不同发色团化合物产生动态和可逆的一维组装,自组装形成的聚集体有助于调节供、受体分子间的距离和偶极方向,提高分子间的能量转移效率,获得可调控的白光凝胶发射材料,该白光凝胶具有对外界明显的刺激响应特性和灵活的相转变过程,以及良好的可塑加工性,在显示材料、照明设备等领域有巨大的潜在应用前景.然而,已经获得的白光凝胶体系存在着在强机械力或高温下会被破坏、凝胶强度低、干凝胶的制备周期长等问题,未来应加强凝胶因子结构和供、受体能量转移效率之间的构效关系研究,以促进白光凝胶工业化应用的尽早实现.Based on the formation mode of white light gel,the research status of constructing white light gel with non-covalent interactions such as hydrogen bonding,π-π stacking and metal complexing was reviewed. It was pointed out that the non-covalent bonding of white light gel could make different chromophore compounds produce a dynamic and reversible one-dimensional assembly,self-assembly of aggregates could help regulate the distance between donor and acceptor molecules and dipole direction to improve the energy transfer efficiency between molecules to obtain a tunable white light gel material. This white light gel had obvious stimulus response characteristics and flexible phase transition to the outside world as well as good plastic workability,and had great potential applications in the fields of display materials,lighting equipment and the like prospect. However,the existing white light gel system had the problems of being destroyed under strong mechanical or high temperature,low gel strength and long preparation period of the dry gel. In the future,the structureactivity relationship research between the gel factor structure and the donor and acceptor energy transfer efficiency should be strengthened to promote the industrialization application of white gel as soon as possible.
