摘要
基于自下而上(bottom-up)的自组装修饰过程制备的纳米功能材料是当下研究的热点。层层组装(Layer-by-Layer Assembly,LbL)是一种简单、通用、高效的制备纳米层状结构的方法。然而,传统LbL要求被组装分子之间具有互补的相互作用力(如静电,氢键给受体作用等)作为成膜驱动力,这个特点阻碍了LbL有效调控薄膜垂直组分结构的能力,并且很难制备没有辅助组装分子的单组份多层纳米结构。本研究中,我们将N-烷基咔唑基团的电化学偶联反应,代替两分子间互补的相互作用引入到纳米粒子层层组装领域,制备了传统方法很难得到的单组份纳米粒子LbL薄膜并方便的调控多种纳米粒子复合物薄膜的垂直组分。通过制备光探测器,我们研究了这种LbL薄膜的光伏性能,并通过调控薄膜组分的方式提升了器件性能。
Layer-by-layer(Lb L) assembly is known as a highly versatile method for fabrication of controlled layered structures from various kinds of materials. However, conventional Lb L methods always need the complementary interaction(such as electrostatic, hydrogen bonding donor and acceptor etc.) between the two assembly components as the driven force, which hampers the versatility of Lb L on effectively tuning the film hierarchical structure. In this study, we introduced electrochemical coupling reaction of N-alkylcarbazole instead of complementary interactions between two assembly components into the nanoparticles(NPs) Lb L filed, facilitating the hierarchical composition manipulating and assembly of single component NPs film. Furthermore, the device performance of photodetector based on this Lb L film can be facilitated optimized via regulating the assembly process.
