Perylene bisimides form a unique class of organic semiconductors, in this investigation two symmetrical perylene bisimides caped with 1-butyl (B-PTCDI) and 4,4-diethoxybutyl (DB-PTCDI) have been synthesized and characterized. The compounds self-assembled as a network of nanobelts and nanorods in the solution based self-assembly process. Morphologies of these self-assembled structures were characterized by optical, fluorescence, scanning and transmission electronic microscopic techniques. One-dimensional self-assemblies of B-PTCDI and DB-PTCDI molecules are due to the strong π-π stacking ability of perylene core and assistance given by the side chains and solvent. Observed molecular self-assembly and electronic properties of the molecules. The observed self-assembly was supported by molecular modeling studies using density functional theory.
并苯双酰亚胺形成了一类独特的有机半导体,在这项研究中,我们合成并表征了两种对称的并苯双酰亚胺,它们分别被 1-丁基(B-PTCDI)和 4,4-二乙氧基丁基(DB-PTCDI)封端。在基于溶液的自组装过程中,这些化合物自组装成纳米带和纳米棒的网络。通过光学、荧光、扫描和透射电子显微镜技术对这些自组装结构的形态进行了表征。B-PTCDI 和 DB-PTCDI 分子的一维自组装是由于并苯核心的强 π-π 堆积能力以及侧链和溶剂的辅助作用。观察到了分子自组装和分子的电子性质。使用密度泛函理论的分子建模研究支持了观察到的自组装。
