Fluorescent citric acid-modified silicone materials†
Abstract
Novel transparent and flexible silicone materials with fluorescent properties were developed. Fluorescent derivative of 2-pyridone was incorporated into silicone matrix via condensation of citric acid with α,β-diamine groups. Obtained materials were characterized according to FT-IR spectra, contact angle and fluorescence properties. Possible applications as sensors and silicone material markers were proposed.
