Dye chemistry
Our interest is directed to the design of dyes for sensing and high-tech applications and to the spectral properties of dyes in solution and solid state. Many types of colour properties related phenomena (aggregation, tautomerism, halochromism, thermochromism, solvatochromism, complexation, NLO activity) have been studied during the years.
