Over the past few decades, pi-conjugated small organic fluorophores have received considerable attention from both academia and industry because of their potential applications in various fields like biological labeling, environmental analysis, optoelectronics etc. Among organic fluorophores, fluorescent heterocyclic compounds like thiazole and pyridine based heterocycles are an important structural motifs of fluorescent molecules and can be utilized to construct the wide variety of multifunctional materials and chemosensors. Further, it is easy to construct donor(D)-acceptor(A) type thiazole...
