摘要: 溶液电沉积法是一种具有沉积时间短,可以常温沉积以及沉积物在基底上附着力高等优点的薄膜制备方法.本文用水合肼增溶苝酰亚胺类化合物(PTCDI)的方法制备了可用于溶液电沉积的苝酰亚胺类化合物溶液.用紫外-可见分光光度法(UV-Vis)对溶解的过程进行了表征,并用顺磁共振(ESR)验证了水合肼对PTCDI的增溶过程实质上是化学反应过程.在制备苝酰亚胺类化合物溶液的基础上,采用阳极电沉积法在ITO导电玻璃上沉积出了薄膜.采用UV-Vis,扫描电镜(SEM)和X射线衍射仪(XRD)对薄膜进行了表征,证实得到了表面较为平整、具有可控结晶结构和形貌的PTCDI薄膜以及具有较宽光谱吸收范围的复合薄膜.

Abstract: Electochemical deposition from solution is a film formation method with advantages of short deposition time and mild conditions. Thereby,obtaining solution of insoluble organic semiconductors(such as perylenetetracarboxyldiimide,PTCDI) for electro deposition is critical to getting their films.In this article,the dissolution process of PTCDI is confirmed by UVVis spectrum and electron spin resonance(ESR).Films of PTCDI 32,PTCDI 179 and composite films of these two are prepared from the solution of single PTCDI and mixture of the two by anode electro deposition,respectively.Characterization by UV-Vis,SEM and XRD show that the films have following characters: flat surfaces,reticular formation,controllable thickness and morphology,wide spectral absorption of the composite films.

Key words: perylenetetracarboxyldiimide, electochemical deposition, film
