Popis: A series of novel naphthopyrans containing fluorine substituents has been prepared and their behaviour following irradiation with UV light has been investigated. The colourless naphthopyrans exhibit photochromism through electrocyclic opening of the pyran ring. The spectral properties of the resulting coloured naphthalene-based dienones are discussed.
