Abstract	Sol-gel SiO2 matrices with Polymethine dyes (РМ1, РМ2 and РМ3) were synthesized using citric acid as a catalyst. There were measured the absorption and luminescence spectra of РМ1, РМ2 and РМ3 dyes (with a concentration of 1·10–5 mole/dm3) in different solvents (ethanol, dimethylformamide, formamide and water) and in sol-gel SiO2 matrices. The said dyes were found to be present in monomeric form in ethanol, dimethylformamide and formamide. PM1 dye did not form dimers in water and in matrices and retained its color. PM2 and PM3 dyes aggregated into the network of SiO2 matrices and in water solution, and the intensity of their coloration reduced in the course of time.
