中文摘要：
利用溶剂引导的无序-有序相转变的方法制备了二噻吩并[3,2-b：2＇,3＇-d]噻吩-2,5-二羧酸（A）和二噻吩并[2,3-b：3＇,2＇-d]噻吩-2,5-二羧酸（B）的自组织薄膜.利用原子力显微镜（atomic force microscopy,AFM）研究了两种化合物分子在基底上的排列方式,发现化合物A分子在云母基底上以一定角度取向排列,而化合物B单分子层在云母基底上以＂平卧＂式排列.结合紫外可见（ultra violet-visible,UV-Vis）吸收光谱、荧光光谱和导电原子力显微镜（conductive atomic force microscopy,C-AFM）对化合物A和化合物B薄膜的光学性质以及微区电子传输行为进行了研究.结果表明,形成J-聚集体的化合物A与化合物B相比,其吸收峰值和发光峰位都发生较大红移,并且化合物A比化合物B的微区电导大三个数量级以上,在基底上的不同聚集结构和取向是导致两种分子微区电导巨大差异的主要原因.
