4,7-di-(2-thienyl)-2,1,3- benzothiadiazole DTBT as active core for synthesizing small molecules to optoelectronic applications: A review
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.
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.
