Side-chain engineering in molecular semiconductors provides a versatile toolbox for precisely manipulating the material's processability, crystallographic properties, as well as electronic and optoelectronic characteristics.
[1]Benzothieno[3,2-b][1]benzothiophene (BTBT) and anthracene (An) are the most promising planar building blocks for constructing p-type small molecules for high-performance organic field-effect transistors (OFETs).
Benzothienobenzothiophene (BTBT) derivatives have been widely studied as excellent organic transistors. In recent years, BTBT derivatives have begun to be used for applications other than transistors and this paper will highlight these applications.
Organic interface between C13-BTBT and Langmuir–Blodgett-prepared PMMA is studied. Favorable molecular adsorption conformation with optimal orbital overlap for high-mobility organic semiconductors and high-degree of surface elasticity are revealed.
Small organic molecules as hole-transporting materials improve perovskite photovoltaic efficiency and stability under indoor conditions, offering a cost-effective and reliable alternative for long-term energy harvesting.
