N-乙基咔唑（NECZ）或咔唑（CZ）与联噻吩（BT）的混合物已被用作在铂电极上形成电沉积聚合物和共聚物膜的单体。当以NECZ-BT混合物开始时，由复合膜循环产生的峰强度随着初始NECZ比例的增加而降低，直到该比例达到40%。对于较高的NECZ比例，无法获得存款。沉积物的红外光谱显示材料中两种单体单元的特征谱带的存在。在CZ-BT混合物的情况下，复合膜的电化学行为接近于分别含有低和高比例CZ的均聚物，即聚联噻吩或二卡巴基所显示的电化学行为。此外，对不同CZ比例获得的沉积物进行红外和紫外可见研究，得到的光谱根据单体比例而变化。(C)2004 Elsevier B. V.保留所有权利。
N-Ethylcarbazole (NECZ) or carbazole (CZ) and bithiophene (BT) have been used as a mixture of monomers for the formation of electrodeposited polymer and copolymer films on platinum electrode. When beginning with a NECZ-BT mixture, the peak intensity resulting from the composite film cycling decreases with increasing initial NECZ proportion until that proportion reaches 40%. For higher NECZ proportions, no deposit could be obtained. Infrared spectra of the deposits show the presence of the characteristic bands of both monomer units in the material. In the case of CZ-BT mixtures, the electrochemical behaviours of the composite films are close to those displayed by the homopolymers, i.e. polybithiophene or dicarbazyle, containing respectively low and high proportions of CZ. Furthermore, infrared and ultraviolet-visible studies of deposits obtained for various CZ proportions yield spectra that vary according to monomer proportion. (C) 2004 Elsevier B.V.
