Fluorescence quenching of organic molecule by insulator
Karunakaran,Jayabharathi,Jayamoorthy
, p. 417 - 421 (2013)
A new kind of fluorophore 2-(4-fluorophenyl)-1-phenyl-1H-benzo[d]imidazole (FPPBI) has been synthesized and characterized by 1H NMR, 13C NMR, mass spectral studies and single crystal XRD. The energy transfer from FPPBI to Al 2O3 nanocrystals has been studied by absorption, fluorescence and lifetime spectroscopic methods. The association between nanoparticles and FPPBI is explained from both absorption and fluorescence quenching data. The distance between FPPBI and Al2O3 as well as the critical energy transfer distance has been deduced.

Aerobic oxidative C-H functionalization of primary aliphatic amines has been accomplished with a biomimetic cooperative catalytic system to furnish 1,2-disubstituted benzimidazoles that play an important role as drug discovery targets. This one-pot atom-economical multistep process, which proceeds under mild conditions, with ambient air and equimolar amounts of each coupling partner, constitutes a convenient environmentally friendly strategy to functionalize non-activated aliphatic amines that remain challenging substrates for non-enzymatic catalytic aerobic systems.

Some fluorescent benzimidazole derivatives have been designed and synthesized using cobalt(ii) hydroxide as highly efficient catalyst. Synthesized compounds have been characterized by 1H and 13C-NMR and mass spectral analysis. The so
Optical properties of 1,2-diaryl benzimidazole derivatives - A combined experimental and theoretical studies
Jayabharathi,Thanikachalam,Jayamoorthy
supporting information, p. 74 - 78 (2013/11/06)
Some novel 1,2-diaryl benzimidazole derivatives have been designed, synthesized and characterized by mass, 1H, 13C-NMR spectral studies and single crystal XRD. The charge distribution has been calculated from the atomic charges by no
Conventional and microwave-assisted synthesis of benzimidazole derivatives and their in vitro inhibition of human cyclooxygenase
Secci, Daniela,Bolasco, Adriana,D'Ascenzio, Melissa,Della Sala, Flavio,Yanez, Matilde,Carradori, Simone
, p. 1187 - 1195 (2013/01/15)
A large series of 1,2-diaryl-benzimidazole and 2-aryl-1H-benzimidazole derivatives were synthesized with slight differences using both microwave irradiation and conventional heating methods. Usually higher yields and time reactions reduction were obtained
