Abstract

Small molecule (SM) organic semiconductor materials have attracted further attention for their significant advancement in light-harvesting devices and optoelectronic applications. Their ease of preparation, well-defined structures, cost-effectiveness, and highly tunable properties promote them for organic solar cells (OSCs), organic field-effect transistors (OFETs), and dye-sensitized solar cells (DSSCs) devices. Conjugated heterostructure donor-π-acceptor SMs have possessed an efficient system for stimulating faster charge transfer and achieving high photon-to-electron conversion. Their structure can be readily modified to incorporate additional π-extension, further elevating their performance in OSCs, DSSCs, and OFETs. Benzothiadiazole, a well-known electron-deficient heterostructure moiety, when flanked by thiophene, has been strongly involved in numerous photoelectronic molecular designs. In this comprehensive review, we will explore the interaction between design strategies, side-chain engineering, molecular structure characteristics, and device engineering, as well as the molecular morphology of 4,7-di-(2-thienyl)-2,1,3-benzothiadiazole (DTBT) based organic SMs on the power conversion efficiency and the charge mobilities in three particular optoelectronic devices: OSCs, DSSCs, and OFETs. The challenges should be resolved with recommendations for DTBT-based molecular architectures for better device performance.

以 4,7-二(2-噻吩基)-2,1,3-苯并噻二唑 DTBT 为活性核心合成光电应用小分子：综述

小分子（SM）有机半导体材料在光收集器件和光电应用方面的巨大进步引起了人们的进一步关注。小分子有机半导体材料易于制备、结构明确、成本效益高且具有高度可调的特性，因此被广泛应用于有机太阳能电池（OSC）、有机场效应晶体管（OFET）和染料敏化太阳能电池（DSSC）器件。共轭异质结构供体-π-受体 SMs 是一种有效的系统，可刺激更快的电荷转移并实现高光子-电子转换率。它们的结构可以很容易地进行修改，加入额外的π-扩展，从而进一步提高它们在 OSC、DSSC 和 OFET 中的性能。苯并噻二唑是一种众所周知的缺电子异质结构分子，当其两侧有噻吩时，它已被广泛应用于许多光电子分子设计中。在这篇综述中，我们将探讨设计策略、侧链工程、分子结构特性和器件工程之间的相互作用，以及基于 4,7-二-（2-噻吩基）-2,1,3-苯并噻二唑（DTBT）的有机 SM 的分子形态对三种特定光电器件中功率转换效率和电荷迁移率的影响：OSC、DSSC 和 OFET。为解决这些难题，我们建议采用基于 DTBT 的分子结构，以获得更好的器件性能。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
