摘　　要：通过多步反应制备了三个新型的双光子吸收化合物,测试了它们的光物理性质,发现该系列化合物具有较大的双光子吸收截面,并且随温度降低其双光子吸收截面增大.尤其是化合物TMVDB,其量子效率为0.83,常温时的双光子吸收截面达到1164GM,其双光子吸收截面除以分子量为2.08,表现出了优良的双光子吸收发光性能.进一步将TMVDB掺杂到固体材料中,得到强双光子诱导发光的固体材料.Three novel distyrylbenzene derivatives have been synthesized and their optical properties have been investigated.All the compounds give large two-photon absorption （TPA） cross sections and their TPA cross sections are significantly enhanced with the temperature decreases.Especially,the compound of TMVDB is highly luminescent as the fluorescence quantum yield of 0.83.TPA cross section of TMVDB is 1164 GM and ratio of TPA cross section divided to molecular weight is as high as 2.08.All the results of TMVDB show its excellent TPA induced emission performance.The TMVDB is doped into the solid matrix and a solid-state film with strong TPA induced emission is obtained.
