合成了一类咔唑－偶氮二元化合物，其分子的吸收光谱中，咔唑环与偶氮部分的吸收叠加形成一特征双峰．调节分子内烷链碳数可有效地控制化合物的熔点．用溶剂化变色法测得这类化合物的二阶极化率与其基态永久偶极矩的复合量约为 ２００ × １０－３０ｅｓｕ·Ｄ．
A class of carbazole-azo binary compounds were synthesized. The absorption spectra of the carbazole ring and the azo moiety overlapped to form a characteristic doublet. Adjusting the number of carbon atoms in the chain can effectively control the melting point of the compound. The complexation of the second-order polarizability and the permanent dipole moment of the ground state measured by solvatochromic method is about 200 × 10-30esu · D.
