合成了电荷转移复合物HEK-TCNQ和HEK-DDQ(HEK=9-hydroxyethylcarbazole)。拉曼光谱和吸收光谱测定表明: 光电导为10^-^1^1s.cm^-^1的HEK-TCNQ在514.5nm激光照射下可发生电荷转移, 生成HEK^+TCNQ^-, 其光电导显著增大。X射线结构分析和红外光谱表明: HEK与DDQ之间基态电荷转移量为0.1~0.2。

The charge transfer complexes of HEK-TCNQ and HEK-DDQ (HEK=9-hydroxyethylcarbazole) have been synthesized. The Raman and UV spectra have shown that under the irradiation at 514.5nm of Ar^+ laser, an electron can be transfered from HEK to TCNQ to form HEK^+TCNQ^-. As a result, the photoconductivity of HEK^+TCNQ^- was measured to be at least one order of magnitude larger than 10^-^1^1s.cm^-^1 of HEK-TCNQ. Based on structural and IR spectra data, the charge transfered from HEK to DDQ in HEK-DDQ was estimated to be 0.1~0.2.
