NOVEL PHENYL NAPTHOL DERIVATIVE

Phenylnaphthol derivatives represented by the following general formula (1), wherein, R 1 to R 3 are hydrogen atoms, alkyl groups or aryl groups, and R 2 and R 3 may be bonded together to form an aliphatic hydrocarbon ring or a heterocyclic ring, a and b are, respectively, integers of 0 to 4, R 4 and R 5 are hydroxyl groups, alkyl groups, haloalkyl groups, cycloalkyl groups, alkoxy groups, amino groups, heterocyclic groups having a nitrogen atom as a hetero atom and are bonded together via the nitrogen atom, cyano groups, nitro groups, formyl groups, hydroxycarbonyl groups, alkylcarbonyl groups, alkoxycarbonyl groups, halogen atoms, aralkylgroups, aralkoxy groups, aryloxy groups, aryl groups, heteroaryl groups bonded together via a carbon atom in the ring, alkylthio groups, cycloalkylthio groups, arylthio groups or heteroarylthio groups, and if R 4 or R 5 are present in a plural number, the plurality of R 4 or the plurality of R 5 may be the same or different, or 2 R 4 s or 2 R 5 s may be bonded together to form an alicyclic hydrocarbon ring or a heterocyclic ring. The compounds are useful as intermediate products for the synthesis of, for example, photochromic compounds.

Substituent effects on the photochromic properties of 3,3-diphenyspiro[benzofluorenopyran-cyclopentaphenanthrene]s

The introduction of electron-donating groups on the skeleton of a naphthopyran, 3,3-diphenyspiro[benzofluorenopyran-cyclopentaphenanthrene], has led to the development of a photochromic dye applicable to photochromic lenses. Introducing a methoxy group to C6 moved the absorption band of the MC form towards the longer wavelength. Further introduction of methoxy groups to the para-position of the phenyl groups on C3 induced faster decoloration of the MC form. Additional introduction of a methoxy group to C13 led to the enhancement of the absorption intensity as well as the facile, economic synthesis of the dye caused by the symmetrical property of the starting material.
