1H-Imidazole derivatives establish one of the iconic classes of ESIPT-capable compounds (ESIPT = excited state intramolecular proton transfer). This work presents the synthesis of 1-hydroxy-4-(2-hydroxyphenyl)-5-methyl-2-(pyridin-2-yl)-1H-imidazole (

First 1-hydroxy-1H-imidazole-based ESIPT emitter with an O–H⋯O intramolecular hydrogen bond: ESIPT-triggered TICT and speciation in solution
Autor: Nikita A. Shekhovtsov, Alexey A. Ryadun, Victor F. Plyusnin, Elena B. Nikolaenkova, Alexsei Ya. Tikhonov, Mark B. Bushuev
Publikováno v: New Journal of Chemistry. 46:22804-22817
In MeCN solution, a 2-aroyl-1-hydroxy-1H-imidazole-based ESIPT emitter exists in a series of forms and shows rather rare excitation wavelength-dependent emission.

Autor: Mark B. Bushuev, Viktor P. Krivopalov, Elena B. Nikolaenkova, Katerina A. Vinogradova, Nikita A. Shekhovtsov
Publikováno v: Journal of Structural Chemistry. 61:1521-1529
DFT and TD-DFT calculations at the B3LYP/LANL2DZ level of theory are performed in order to explain the origins of dual fluorescence and uncover the relaxation pathways of 2-amino-4-methylpyrimidine (L). The computations are in good agreement with exp

SPIN TRANSITION IN HETEROANION COMPLEXES IN THE Fe2+-4-AMINO-1,2,4-TRIAZOLE–$$\text{NO}^{-}_3$$–$$\text{SO}^{2-}_4$$ SYSTEM
Autor: Mark B. Bushuev, Denis P. Pishchur, Katerina A. Vinogradova, A. Yu. Andreeva
Publikováno v: Journal of Structural Chemistry. 61:1380-1389
Magnetic and thermodynamic properties of heteroanion complex compounds in the Fe2+–ATrz– $$\text{NO}^{-}_3$$ – $$\text{SO}_4^{2-}$$ (ATrz = 4-amino-1,2,4-triazole) system are studied. The Fe(ATrz)3(NO3)2(1–x)(SO4)x·nH2O phases are synthesize

Excitation wavelength dependent emission of silver(i) complexes with a pyrimidine ligand
Autor: Katerina A. Vinogradova, Nikita A. Shekhovtsov, Viktor P. Krivopalov, Mark B. Bushuev, Elena B. Nikolaenkova, Alexey S. Berezin, Taisiya S. Sukhikh
Publikováno v: Inorganic Chemistry Frontiers. 7:2212-2223
Silver(I) complexes with 2-amino-4-phenyl-6-methylpyrimidine (L), [Ag3L2(H2O)0.55(NO3)3]n (1) and [Ag2L2(PPh3)2(NO3)2] (2), have been synthesized and structurally characterized. In the solid state the free ligand L demonstrates dual fluorescence: a h
