Synthesis characterization photophysical evaluation and sensor applications of benzimidazoquinoline and its derivatives

Abstract

In the recent years, fluorescent compounds for chemical and biological applications have grown markedly and it is found to be one of the real-time applicationsspecifically in quality control environmental monitoring and cellular imaging. Consequently, the synthesis and characterization of new fluorescent probes are become a vibrant in the field of supramolecular chemistry. Many of the reported fluorescent probes can act as dye for cell imaging studies and molecular sensor for particular species like metal ion and anionic species. It also found to be importance for the sensing of molecular level environmental factors such as pH, solvent polarity and so on. Recently the establishment of a single probe system having the ability of multiple species detection is further aspired due to the vast need in different fields of field related and economical way of applications. With this background of reviews in our mind, we synthesized fluorescence active compound Benzimidazoquinoline derivatives namely, 2-chloro-3-(6-methyl-1H-benzol-2-yl)quinoline (AVMPDA), 3-(6-methyl-1Hbenzo[d]imidazol-2-yl)quinoline-2(1H)-one (AVMPDO), 2-(3-(6- ethyl-1Hbenzo[d]imidazol-2-l)quinolin-2-yloxy)ethanol (AVMPDG), 2-(2-(3-(6-methyl-1H-benzo[d]imidazol-2-yl)quinolin-2-yloxy)ethaoxy)ethanol (AVMPDDG), 3-(1H-benzo[d]imidazol-2-yl)quinolin-2(1H)-one(AVPDO) and 2-(3-(6-methyl-1H-benzo[d]imidazol-2-yl)quinolin-2-ylthio)ethanol (AVPDSG). They were characterized by spectroscopy techniques using IR and NMR [1H and 13C]. Mass spectral study of AVPDSG and single crystal X-ray diffraction study of the compound AVPDO confirmed the structure of all the derivatives. newline
