چکیده انگلیسی
ⶠSol-gel technique was used to obtain silica based hybrid materials containing benzimidazole dyes. ⶠThe sol-gel catalysts, HF and NaF, produce xerogels with different optical and textural characteristics. ⶠHigh pressure technique (6.0 GPa) was used to produce fluorescent and transparent silica compacts with the dyes entrapped in closed pores, maintaining their optical properties. ⶠThe excited state intramolecular proton transfer (ESIPT) mechanism of benzimidazole dyes was studied by steady-state fluorescence spectroscopy for the monoliths, powders, and compacts.
