A series of three-dimensional, star-shaped narrow band-gap conjugated donor-π-acceptor (D-π-A) molecules were designed and synthesized.These molecules comprised electron-rich triphenylamine as the core (donor) and an assortment of electron-deficient pendant groups as the arms (acceptor), and were connected through a thiophene unit as the π-bridge.Systematical alternation of the pendant acceptor groups from symmetric to asymmetric architectures afforded molecules with versatile optical, electrochemical as well as photovoltaic properties.

石墨烯作为一种新型的材料,具有特殊的二维结构,在力学、热学、电学、光学等方面表现出优异的性能,近年来吸引了研究者的广泛关注.2011年Geok-Kieng Lim报道了单层石墨烯的宽带非线性光学性质,在含有重原子的溶剂和薄膜状态下,随着激光能量的增加,表现出极好的光限幅效应[1].尽管石墨烯非线性光学性质的机理尚不明确,但其优异的非线性光学性质为激光防护材料设计提供了新的选择.

可溶液法加工的有机薄膜晶体管(organic thin-film transistor, OTFT)器件是实现印刷有机电子信号处理、控制与传输功能的基础元件.近十年,国内外大量的研究工作集中于发展高迁移率的可溶性有机聚合物和小分子半导体材料,所报道的载流子迁移率已能远远超过了非晶硅的水平.除了半导体材料外,可溶液法加工的绝缘层和导电材料的研究也开始获得重视,与半导体材料匹配,可以形成全溶液法或印刷
有机电致发光器件(OLED)在平板显示和照明领域受到人们的广泛关注.然而与技术成熟的液晶显示(LCD)相比较,OLED需要进一步降低其功耗和驱动电压[1,2].为此,增强载流子从电极的注入和提高它们在发光层中的平衡程度是非常重要的.在本文中,我们制备了含NaCl∶Bphen复合电子传输层的有机电致发光器件,其结构为:ITO/NPB(40nm)/DSA-ph(20nm)/Bphen(20nm)/Na
Solution processed organic solar cells (OSCs) based on small molecules often suffer from low charge mobilities when blended with fullerene derivatives partly due to the non-crystalline and amorphous m
