Sensitivity of the phenoxy derivatives of 2,4-dihydro-5H-[1,2,3]triazolo[4,5-d]pyrimidin-5-ones to acidic and basic stimuli

Herein we report the research on the sensitivity of six hydroxy derivatives of dihydrotriazolopyrimidines (HO-DTP) to acids and bases. The UV/Vis and fluorescence spectra of these compounds were investigated with the addition of the acids and bases. Spectral data revealed the strong red shifts for e...
