摘要
双光子吸收材料在诸多领域如光限幅、双光子上转换激射、双光子荧光显微术、三维光存储以及三维微加工等方面有潜在的应用前景。近年来,对有机双光子吸收材料的研究正成为材料领域研究的热点之一。杂环化合物由于具有优良的双光子性质,高的光学稳定性,因而成为研究的重点。对杂环简单的化学修饰,就可以实现对材料的最大吸收波长和发射波长大范围的调节。同时杂环化合物一般具有较强的推拉电子能力,能有效的提高双光子上转换激射效率,是一类很有发展潜力的双光子材料。
Materials of large two-photon absorption （TPA） behavior have potential application prospects such as optical power limiting up-converted lasing, two-photon fluorescence excitation microcopy, threedimensional optical data storage, photodynamic therapy and microfabrication. Recently, the study of organic two-photon absorption materials has become a hot issue in the field of materials. Due to the excellent two-photon nature of the high optical stability, the heterocyclic compounds thus become the focus of the study. Heterocyclic of simple chemical modification can be achieved on the wavelength of maximum absorption material and emission wavelength of a wide range of adjustment. At the same time, heterocyclie compounds in general have a strong push and pull of electronic capabilities, they can effectively raise the two-photon laser-conversion efficiency. This kind of compounds is a sort of great potential for development of two-photon materials.
