Thiazole and its derivatives play an important role in biological non-biological fields due to several structural electronic behaviors associated with it. act as chemosensors because they formed metal complexes upon interacting various heavy ions like Cd2+, Co2+, Cr3+, Fe3+, Ag+, Al3+, Cu2+, Pd2+, Hg2+, Ni2+, Ga3+, In3+, Sn4+, Pb2+, Zn2+ well other cations. These are of prime importance from the environmental point view high. This review article focuses on thiazole-based colorimetric fluorometric sensor for recognition different cations specimens agricultural, biological, environmental. It also summarizes binding stoichiometry, detection limit, pH, structure, practical application reported chemosensors. Further, sensing performances, have been discussed compared some organic sensors.

In the present study, novel benzimidazole compounds are synthesized, utilizing Suzuki coupling and acid-amine reaction. The formation of all synthesized derivatives was confirmed through various spectroscopic techniques, including 1H, 13C, Carbon DEPT-135, H-H COSY, HSQC, HRMS. UV-Vis fluorescence spectra were recorded. Particularly, among compounds, compound 9o (304.06 nm) exhibited higher λmax in spectroscopy, while 9j (396.16 highest emmision intensity spectroscopy. Furthermore, density functional theory (DFT) calculations performed at B3LYP/6-31G'(d,p) foundational level set. These aimed to predict chemical reactivity newly by assessing parameters such as HOMO-LUMO energy gap value, ionization potential, electrostaic electron affinity, electronegativity, global hardness, softness values. Subsequently, a molecular docking analysis on protein associated with Bcl-2 conjunction venetoclax, 9g (-10.77 kcal/mol) indicating most significant binding affinity investigated.
