Abstract

Abstract : In this study, the synthesis of a series of bay‐substituted donor–acceptor–donor (D–A–D) type perylene diimide derivatives (3a–3d) has been reported as an acceptor for the small‐molecule‐based organic solar cells (SM‐OSCs) by the Suzuki coupling method. It has been evaluated for the antimicrobial activity against some of the bacteria and fungi. The synthesised SMs were confirmed by Fourier transform‐infrared spectroscopy, nuclear magnetic resonance (NMR), and high resolution mass spectroscopy (HR‐MS). The SMs showed absorption up to 750 nm, which eventually reduced the optical band gap E g opt to < 2 eV. SMs showed thermal stability up to 400 °C. In the SM‐OSC, the SMs showed a power conversion efficiency of < 1% with the P3HT donor in bulk hetero‐junction device structure. Additionally, the new SMs showed antimicrobial activity against Gram‐negative bacteria such as Escherichia coli Gram‐positive bacteria such as Bacillus subtilis and antifungal activity against the Candida albicans, and Aspergillus niger . Cytotoxicity studies were carried out against the breast cancer cell lines MCF‐7 using MTT assay method. The results revealed that the SMs was able to inhibit the cancer cells. LD50 s calculated for the SMs 3a–3d were between 200 and 400 µg/ml.
