Photochemistry and photopolymerisation of substituted 2-methylanthraquinones
Home > news

Anthraquinones have been the subject of numerous photochemical studies and their photopolymerization activities have been examined under various conditions to improve more efficient photochemical systems. 

This article involves further detailed investigations into the photophysical, photochemistry and photopolymerisation properties of 4 commercial derivatives of 2-substituted anthraquinone, namely, 2-Bromomethylanthraquinone (2BA), 2-Chloromethylanthraquinone (2CA), 2-Ethylanthraquinone (2EA), 2-Hydroxymethylanthraquinone (2HA) and one novel synthesized anthraquinone, 2-Acryloxymethylanthraquinone (2AA). 

2AA is synthesized from 2HA. The results from both spectroscopic and analysis studies proved the 2AA to having the ester link. Absorption spectroscopy and solvent shift data are used to characterise their spectral activity. Luminescence studies involving fluorescence and phosphorescence analysis indicates efficient intersystem crossing to triplet state and n-¦Ð* nature of the lowest excited triplet state.
