摘要
通过Wittig和Heck反应合成了目标产物YZ1和YZ2,研究了分子的"枝"数和纳米粒子对材料的双光子性能的影响。实验结果表明,增加分子的枝数有利于提高材料的双光子吸收截面,双枝YZ2的最大双光子吸收截面为1 271 GM。另外,纳米粒子的加入有利于提高YZ1和YZ2的双光子荧光强度。
Two compounds YZ1 and YZ2 were synthesized through the reaction of Wittig and Heck.The affect of the ＂branches numbers＂ in the molecule and nanoparticles on the two-photon properties of compounds YZ1 and YZ2 were studied.The results show that the two-photon absorption cross section（δTPA） is enhanced with the increase of branch number,and the maximum δTPA of compound YZ2 is 1 271 GM.Additionally,the addition of the nanoparticles can help to improve the δTPA of compounds YZ1 and YZ2.
