Journal ArticleDOI
Spectroscopic analysis and DFT calculations of a food additive Carmoisine
TL;DR: Intramolecular charge transfer responsible for the optical nonlinearity of the dye molecule has been discussed theoretically and experimentally and the first hyperpolarizability of the molecule is calculated.
Journal ArticleDOI
Design, synthesis, antimicrobial activity and computational studies of novel azo linked substituted benzimidazole, benzoxazole and benzothiazole derivatives.
Virendra R. Mishra,Chaitannya W. Ghanavatkar,Suraj N. Mali,Shahnawaz I. Qureshi,Hemchandra K. Chaudhari,Nagaiyan Sekar +5 more
TL;DR: Novel azo linked substituted benzimidazole, benzoxazoles, and benzothiazole were synthesized by diazo coupling and characterized by 1H NMR, elemental analysis, FTIR and UV-vis spectroscopy, and the comparative molecular docking studies revealed better insights into binding mechanisms.
Journal ArticleDOI
Fluorescent azo disperse dyes from 3-(1,3-benzothiazol-2-yl)naphthalen-2-ol and comparison with 2-naphthol analogs
TL;DR: In this paper, five fluorescent azo disperse dyes were synthesized using different diazotized aromatic amines followed by coupling with 3-(1,3-benzothiazol-2-yl)naphthalen-2 -ol.
Journal ArticleDOI
Carbazole-Linked Near-Infrared Aza-BODIPY Dyes as Triplet Sensitizers and Photoacoustic Contrast Agents for Deep-Tissue Imaging
Yogesh Gawale,Nagappanpillai Adarsh,Sandeep Kumar Kalva,Joshy Joseph,Manojit Pramanik,Danaboyina Ramaiah,Nagaiyan Sekar +6 more
TL;DR: The uniqueness of these new N-ethylcarbazole-linked aza-boron-dipyrromethene (aza-BODIPY) dyes is that they exhibit efficient triplet-state quantum yields, high singlet oxygen generation yields, and good photostability.
Journal ArticleDOI
Synthesis of new ESIPT-fluorescein: photophysics of pH sensitivity and fluorescence.
Vikas S. Patil,Vikas S. Padalkar,Kiran R. Phatangare,Vinod D. Gupta,Prashant G. Umape,Nagaiyan Sekar +5 more
TL;DR: ESIPT-inspired benzimidazolyl substituted fluorescein dyes were synthesized and PH-sensitivity was determined by the photophysical property measured at a physiological possible pH range.
