Abstract
Novel benzo[ de]anthracen-7-one yellow–green and orange–red fluorophores, containing a hindered amine stabiliser fragment have been synthesised and their ability for “one-step” mass or chemical colouration and stabilisation of poly(methyl methacrylate) has been demonstrated. Two of the synthesised compounds, containing a polymerisable group, were co-polymerised with methyl methacrylate. The chemical bonding of the monomers in the polymer chain was confirmed spectrophotometrically. The absorption and some basic photophysical characteristics of the low and high molecular weight fluorescent dyes have been determined. Photostability of the novel fluorophores and their influence on the photostability of the fluorescent side-group co-polymers obtained have been established. A significant stabilising effect against photodegradation was determined.
