酞菁铜溶解性研究及其电沉积薄膜的制备

通过测定α-酞菁铜(α-CuPc)在4种不同的有机溶剂中的紫外可见光吸收光谱,研究了不同溶剂以及加入不同量的三氟乙酸(TFAA)对酞菁铜溶解性和质子化的影响.以溶解性研究为基础,探讨了在电化学沉积法制备酞菁铜薄膜时不同工艺条件对其形貌的影响.实验结果表明:加入TFAA后,酞菁铜在硝基甲烷和氯仿中溶解良好,而且在氯仿中更容易质子化;使用扫描电镜(SEM)表征,结果表明TFAA及酞菁铜摩尔含量对薄膜制备的影响最为明显.

Dissolving and Electro-Chemical Deposition of Copper Phthalocyanine

In order to obtain the ideal Copper Phthalocyanine(CuPc) film from organic solution,first,we studied the solubility of CuPc in different solvents,and the effect of various amounts of trifluoroacetic acid(TFAA) to CuPc;Second,we fabricated CuPc films with different electro-chemical deposition conditions,and discussed the changes of the surface morphology.Then using the UV-Vis to measure the spectrum of copper phthalocyanine(CuPc) in four different organic solvents;using the scanning electron microscopy(SEM) to observe the surface morphology of CuPc films.The results showed that: after adding TFAA,CuPc is easily dissolved in both nitro-methane and chloroform,but in chloroform,it is more easily protonated;the amount of TFAA and CuPc has great influence to the surface morphology.
