杂螺烯圆偏振发光材料的研究进展

Heterohelicenes represent a class of polycyclic aromatic hydrocarbons (PAHs) with helically chiral structures, and in recent years these compounds and their derivatives have emerged as a research focus in the field of chiral luminescent materials due to their unique optical properties and circularly polarized luminescence (CPL). This review comprehensively summarizes the modulation mechanisms by which the incorporation of main-group elements (e.g., N, O, S) regulates the electronic structures, luminescence performance, and chiroptical properties of helicenes. The recent advances in the design of CPL materials based on heterohelicenes that are doped with N, O, S or B/N, O/N, S/N is introduced in detail, and their potential applications in 3D displays, information encryption, and bioimaging are prospected. Therefore, studies on the synthesis, structural design, and photophysical properties of heterohelicene-based CPL-active molecules hold significant importance in advances of optoelectronics and materials science.
