摘　　要：标题化合物是一种商品名为Agfa-10的份菁染料,是一种光导性能较好的有机光导体。我们已对它的蒸发膜、溶液膜、单晶的培养与结构,晶型的转变及其电子性能进行了系统地研究与报导.它具有如下的分子结构:The merocyanine dye 3-ethyl-5-(2-(3-ethyl-2-benzothiazolinylidene)-ethylidene)rhodanine (BTER) known as Agfa-10 has been found to have a good photoconductivity as solution cast film. In this paper iodine-doped BTER was obtained by dopingwith iodine vapor. Its structure was investigated with the following characteristies. 1 The doped iodine had been excited as I_3^- anion. 2 Because the electron located on the sulphur atom was transferred to iodine, the charge transfer complex of (BTER-I_3) formed. 3 During the iodine doping process, BTER changed from α-form to β-modifica- tion. These had been identified by X-ray diffraction, VIS-absorption spectra and SEM picture. 4 From the volt-Ampere curve obtained from sandwich cell, when E≤2.2×10^(-1) V·cm^(-1), the room temperature electrical conductivity of BTER and BTER-I_3 were found to be 2. 22×10^(-10) S·cm^(-1) and 2.6×10^(-7) S·cm^(-1), respectively.
