中文摘要：
自我组织的 dithieno [3,2-b:2,3-d ] thiophene-2,5-dicarboxylic 酸(A) 和 dithieno [2,3-b:3,2-d ] thiophene-2,5-dicarboxylic 酸(B) 电影通过导致溶剂的顺序混乱转变被准备方法。底层上的二个分子的安排被原子力量显微镜学(AFM ) 观察，它证明 A 被安排在云母上的某个角度有序，当 B 在云母上是扁平飞的时。光并且在这二部复合电影的微区域的传导力性质被紫外力的吸收光谱学，荧光光谱学和传导性的原子力量显微镜学(C-AFM ) 描绘。结果表明 A 的荧光和吸收山峰 B 与那些比较有大红移动。为 A 的 J 总数的传导力比 B 的高是三订单大小。大传导力差别主要在底层上来自不同聚集结构和这二个分子的取向，这被结束。
英文摘要：
Self-organized dithieno [3,2-b：2′,3′-d] thiophene-2,5-dicarboxylic acid （A） and dithieno [2,3-b：3′,2′-d] thiophene-2,5- dicarboxylic acid （B） films were prepared through solvent-induced order-disorder transition method. The arrangement of the two molecules on substrates were observed by atomic force microscopy （AFM）, which demonstrated that A was arranged orderly in a certain angle on mica, while B was fiat-flying on mica. The optical and conductance properties in micro region of these two compound films were characterized by UV-vis absorption spectroscopy, fluorescence spectroscopy and conductive atomic force microscopy （C-AFM）. The results revealed that the fluorescence and absorption peaks of A had a large red shift in comparison with those orB. The conductance of the J-aggregates for A is three orders magnitude higher than that of B. It is concluded that the large conductance difference mainly comes from different aggregation structures and orientations of these two molecules on substrate.
