Pyrimidine-Based Push–Pull Systems with a New Anchoring Amide Group for Dye-Sensitized Solar Cells

New donor–π–acceptor pyrimidine-based dyes comprising an amide moiety as an anchoring group have been designed. The dyes were synthesized by sequential procedures based on the microwave-assisted Suzuki cross-coupling and bromination reactions. The influence of the dye structure and length of π-linker on the photophysical and electrochemical properties and on the photovoltaic effectiveness of dye-sensitized solar cells was investigated. An increase in efficiency with a decrease in the length of π-linker was revealed. The D1 dye with only one 2,5-thienylene-linker provided the highest power conversion efficiency among the fabricated dye sensitized solar cells. © 2021 by the authors.IGIC RAS, (AAAA-A20-120101490004-4)Russian Foundation for Basic Research, РФФИ, (18-29-23045)Ministry of Education and Science of the Russian Federation, Minobrnauka, (AAAA-A19-119011790132-7)This work (optical and electrochemical properties) was supported by the Russian Foundation for Basic Research (Project No. 18-29-23045 mk).
