Synthesis and Photophysics of Some Novel Imidazole Derivatives Used as Sensitive Fluorescent Chemisensors

Fluorescence resonance energy transfer from a bio-active imidazole derivative 2-(1-phenyl-1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol to a bioactive indoloquinolizine system

“…Therefore, imidazole derivatives have been used to construct highly sensitive fluorescent chemisensors for sensing and imaging of metal ions and its chelates in particular those with Ir 3+ are major components for organic light emitting diodes [1] and are promising candidates for fluorescent chemisensors for metal ions. In continuation of our recent research experimental results [6][7][8][9][10][11][12][13][14][15], in the present paper we summarized a comprehensive study of the imidazole derivative and its structure was characterized by NMR spectra. Photophysical, photochemical studies, its chemisensor behaviour and FRET studies were analyzed and discussed.…”

Photosensitization of Imidazole Derivative by ZnO Nanoparticle

“…The experimental procedure used was the same as described in our recent works [32][33][34][35][36][37][38][39][40][41]. The imidazole derivative was synthesized by three components assembling of benzil (40 mmol), ammonium acetate (30 mmol) and cinnamaldehyde (30 mmol).…”

Antioxidant potential and antimicrobial screening of some novel imidazole derivatives: greenway efficient one pot synthesis

“…General procedure for the synthesis of 2-aryl imidazole derivatives A mixture of aldehyde (1 mmol), 1,2-diketone (1 mmol), ammonium acetate (2.5 mmol), and iodine (15 mol%) were grined in a mortar at room temperature for 2 h. The completion of the reaction was monitored by TLC and the reaction mixture was treated with aqueous Na 2 S 2 O 3 , the formed crude was purified by column chromatography (Jayabharathi et al, 2009(Jayabharathi et al, , 2010aSaravanan et al, 2010) (n-hexane:ethyl acetate (9:1) (Scheme 1).…”
