Abstract：
Self-assembly of chromophoric systems is a prerequisite to create well-ordered, processable nanomaterials with multiple functionalities. In the past two decades, the field of functional organic materials has primarily focused on systems featuring only one type of dye/π-conjugated unit. Consequently, many reports with mechanistic insights on the self-assembly of the dyes featuring different molecular packing have been reported. Subsequently, we have witnessed several attempts to organize the multi-chromophoric systems in solution and solid-state via different approaches using self-assembly as a tool. Incorporation of more than one dye is important in creating materials with tuneable optoelectronic properties. Consequently, self-assembly of more than one chromophoric systems have been investigated to some extent. This review aims to discuss the self-assembled materials derived from discrete π-conjugated systems comprising more than one dye units connected through covalent bonding (multi-chromophoric systems). Molecular design of various multi-chromophoric systems leading to the formation of crystals, liquid crystals and supramolecular polymers have been correlated with corresponding properties. We envisage that classification of self-assembled multi-chromophoric systems, with a note on tuneable optoelectronic properties, can provide a deeper understanding on the molecular design strategies, which is important in the fabrication of functional organic materials with optimum performances.
摘要：
发色系统的自组装是创建有序，具有多种功能的可加工纳米材料。在过去的二十年里，功能有机材料领域主要集中在仅具有一种类型的染料/π-共轭单元的系统上。因此,已经报道了许多关于具有不同分子包装的染料的自组装的机械见解的报道。随后，我们已经目睹了几次尝试通过使用自组装作为工具的不同方法在溶液和固态中组织多发色系统。多于一种染料的掺入在产生具有可调谐光电性质的材料中是重要的。因此,已经在一定程度上研究了一种以上发色系统的自组装。本文旨在讨论衍生自离散π共轭系统的自组装材料，该系统包含多个通过共价键合连接的染料单元（多发色系统）。各种多发色系统的分子设计导致晶体的形成，液晶和超分子聚合物已经与相应的性质相关。我们设想自组装多发色系统的分类，关于可调光电特性的注释，可以对分子设计策略有更深入的了解，这对于制造具有最佳性能的功能有机材料非常重要。
