Light-Driven Switching between Intramolecular Proton-Transfer and Charge-Transfer States

Autor: Govindarajan Krishnamoorthy, Minati Das, Mongoli Brahma

Publikováno v: The Journal of Physical Chemistry B. 125:2339-2350

A molecular photoswitch, 2-(4'-diethylamino-2'-hydroxyphenyl)-1H-imidazo-[4,5-b]pyridine (DHP), with mutually independent paths of excited-state intramolecular proton transfer (ESIPT) and twisted intramolecular charge transfer (TICT) was developed. C

Modifying the proton transfer of 3,5-bis(2-hydroxyphenyl)-1H-1,2,4-triazole by water, confinement and confined water

Autor: null Ila, Mongoli Brahma, Sanjeev Ranjan, Pravesh Tripathi, G. Krishnamoorthy

Publikováno v: Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy. 272

The effect of water, confinement and confined water on the proton transfer of 3,5-bis(2-hydroxyphenyl)-1H-1,2,4-triazole (bis-HPTA) was investigated. Water alters the proton transfer process. At higher pH, an anion is formed in water and it undergoes

Host-guest interaction aided Zinc carry and delivery by ESIPT active 2-(2′-hydroxyphenyl)benzoxazole

Autor: Minati, Das, Mongoli, Brahma, G, Krishnamoorthy

Publikováno v: Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy. 281:121474

The effect of solvents and supramolecular hosts on the binding of metal ion with an excited state intramolecular proton transfer (ESIPT) active fluorophore 2-(2'-hydroxyphenyl)benzoxazole (HPBO) are investigated to scrutinize a possible metal ion car

Controlling the photoswitching of 2-(4′-diethylamino-2′-hydroxyphenyl)-1H-imidazo-[4,5-b]pyridine by pH

Autor: Mongoli Brahma, Minati Das, Govindarajan Krishnamoorthy

Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 421:113504

2-(4′-Diethylamino-2′-hydroxyphenyl)-1H-imidazo-[4,5-b]pyridine (DHP) has two mutually independent reaction paths, excited state intramolecular proton transfer (ESIPT) and twisted intramolecular charge transfer (TICT). To uncover the effect of ac
