fluorine atoms are brought closer together (see Fig. 2). The distance between the axial fluorine atoms and the hydrogen atoms is only 240 pm; however, no evidence of H...F bridges is apparent from the spectroscopic data. The SCF geometrical optimization shows that the isomer with an equatorially or

## Abstract Crowned chromenes βˆ’ four novel naphthopyrans (chromenes) bearing monoaza‐12‐crown‐4, ‐15‐crown‐5, ‐18‐crown‐6, and a noncyclic analogue at the 5‐position βˆ’ were synthesized, and their photochromism in acetonitrile was examined in the presence of alkali and alkaline‐earth metal ions.
