Synthesis of fluorescent [1,2,4]triazolo[1,5- a ]pyrimidines and study of their photophysical behavior

Year: 2026

Type: article

Abstract: = 98% in THF at ∼450 nm; turn-off fluorescence to 10% in water and with TFA; LOD of 9.0-12.6 µM), due to intramolecular charge transfer (ICT) within the 7-arylated heterocyclic core; this process is altered by a methyl substituent on the triazole moiety. DFT and TD-DFT calculations were used to correlate the spectroscopic properties of eight of the synthesized products.
