Abstract: Abstract New conjugated dye C1 (2, 2′-((5-(2-(4-methoxyphenyl)ethenyl)-benzene-1, 3-diyl)-bis-(nitrilomethylylidene))-diphenol) carrying double proton transfer segments and its reference C2 (N, N′-(5-(2-(4-methoxyphenyl)-ethenyl)-benzene-1, 3-diyl)-bis-(1-phenylmethanimine)) were synthesized. The SEM and TEM images showed that cubic-shaped aggregates of C1 were formed… read more here.

DOI: 10.1038/s41598-020-66530-8
Abstract: To induce double-proton transfer (DPT) with guanine in a biological environment, 12 cytosine analogues (Ca) were formed by atomic substitution. The DPT reactions in the Watson–Crick cytosine–guanine model complex (Ca 0 G) and 12 modified… read more here.

Abstract: The reaction of 1-dimethylamino-8-(methylamino)naphthalene with 1,3-dibromopropane chemoselectively leads to the product of N,N′-heterocyclization, while in the case of 1,4-dibromobutane and 1,2-bis(bromomethyl)benzene the process results in heterocyclization onto the same nitrogen atom with the formation of… read more here.

DOI: 10.3390/molecules26144373
Abstract: Using dynamic liquid-state NMR spectroscopy a degenerate double proton tautomerism was detected in tetramethyl reductic acid (TMRA) dissolved in toluene-d8 and in CD2Cl2. Similar to vitamin C, TMRA belongs to the class of reductones of… read more here.
