π-Conjugated organic semiconductor materials (OsCMs) have gained significant attention for their potential applications in optoelectronic devices like organic light-emitting diodes (OLEDs), organic field effect transistors (OFETs), solar cells, sensors, photorefractive devices, memory devices, and batteries. These materials offer advantages such as low cost, excellent solubility in organic solvents, transparency, light weight, mechanical flexibility, processability, and broad range tunability. They can be synthesized using environmentally benign synthetic methodologies. The molecular design of OsCMs is crucial for obtaining optimal optoelectronic properties. several molecular design strategies have been established to decrease the band gap of π-conjugated molecules, with the "push-pull" or "donor-acceptor" (D-A) type being the most successful. Thiazole-based compounds have been introduced as organic semiconductors since the 1990s due to their promising optical and electronic properties. Research has shown that the optoelectronic properties of TBsCMs strongly depend on the electronic nature of the substituents on the thiazole core and their combinations. Preparing D-A type TBsCMs is easy by introducing a wide variety of electron-withdrawing and electron-donating substituents at different positions of the thiazole nucleus. The PI is interested in designing and developing a new class of highly π-conjugated D-A type TBsCMs for optoelectronics. The proposed D-A type TBsCMs will be synthesized from readily available starting materials using simple, economic, and environmentally benign synthetic routes. The synthesized D-A type TBsCMs will be characterized using spectral and analytical techniques, and their optical and electronic properties will be investigated.
