摘　　要：近年来,共轭梯形聚合物由于良好的化学和热稳定性以及优异的光电性能受到了研究人员的广泛关注.共轭梯形聚合物的主链重复单元被各种桥联结构最大程度限制在同一平面内,因此和传统的共轭聚合物相比,共轭梯形聚合物具有更大的π共轭体系和电子离域性,这使得共轭梯形聚合物具有更高的荧光量子效率和电荷迁移率.在已报道的合成方案中,结构缺陷和溶解性差是共轭梯形聚合物面临的最大问题.结构缺陷会导致材料性能降低,而溶解性差会影响材料的表征和应用.本文综述了共轭梯形聚合物最新的合成进展和解决结构缺陷及溶解性差的途径,同时还包括其在光电器件领域的一些应用研究,并对其在更多领域的应用进行了展望.Conjugated ladder polymers(cLPs)have attracted much attention due to their excellent chemical,thermal stability and excellent photoelectric properties.In contrast to conventional conjugated polymers,cLPs have moreπ-conjugation and delocalization of electrons because the repeated units in the main chain of ladder polymer are restricted to form planar structure by various bridges.Thus,cLPs exhibit high quantum efficiency and fast charge mobility.The challenges in the synthesis of cLPs are the structural defects and solubility which limits the characterization and application.In this review we describe the new synthetic routes and strategies to cLPs with higher solubility;their applications in optoelectronics devices fields and other potential fields are also summarized.
