Abstract
The charge transfer complexes of HEK-TCNQ and HEK-DDQ (HEK = 9-hydroxy ethylcarbazole) have been synthesized. The Raman and UV spectra have s hown 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 on e order of magnitude larger than 10(-11)S.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 similar to 0.2.
