| 摘 要： | 利用简并四波混频（ＤＦＷＭ）方法测量二元分子卟啉酞菁的三阶非线性极化系数Ｘ（３）值．得到二元分子卟啉酞菁的ｘ（３）值比它们单元分子卟啉、酞菁的ｘ（３）值大；二元分子卟啉酞菁的ｘ（３）值起初是随链长的增加而增加，链长增至ｎ＝３时，ｘ（３）值达到最大值．当链长进一步增加时，二元分子卟啉酞菁的ｘ（３）值反而下降．这同二元分子中卟啉、酞菁分子由柔性链连接有关．本文对结果给出可能的解释．

| Abstract: | The values of third-order susceptibilities X(3) of porphyrin-phthalocyanine heterodimers have been measured by degenerate four-wave mixing (DFWM) method. The third-order susceptibilies X(3) of the heterodimers are more than that of free base porphyrin (H2TTP) and phthalocyanine (H2Pc); the X(3) values of porphyrin-phthalocyaine heterodimers first increase directly proportional to the chain length between porphyrin and phthalocyalocyanine value reaches the largest when the chain length equal the number of the 3 methylene. Then the X(3) values of heterodimers decrease even though the chain lengths increase further. These results are related to flexible chains which are covalently-linked porphyrin and phthalocyanine. We give a tentative explanation for these results. |
