AB - This study reports the synthesis of nine new fluorescent stilbene‐triazine whitening agents containing a tetramethylpiperidine fragment. These products were isolated and characterised by spectroscopic techniques, i.e. infrared, ultraviolet, and fluorescent spectra, and confirmed by proton nuclear magnetic resonance spectroscopy. The photostability of the new compounds and two optical brighteners containing an unsaturated group without a stabiliser fragment was studied. It was found that the compounds containing tetramethylpiperidine have better photostability. The possibility of the copolymerisation of the unsaturated compounds with acrylonitrile was investigated, and self‐whitening polymers with an intense blue fluorescence were obtained. It was established that 85–86% of the fluorophores are chemically bound to the polymer chain.
