Studies in Naphthopyran chemistry
… been synthesized by the reduction of the related naphthopyranones and dehydration of the resulting pyranols. The latter reaction was accompanied by dimerised and polymerised material in the [1,2-b] and [2,3-b] series. Some reactions of the pyran double bond have been studied in order to assess the …

Design and synthesis of mechanoresponsive materials and multivalent polymer-peptide conjugates
… on the mechanochemical reactivity of a naphthopyran mechanophore is examined. A series of constitutional isomers was evaluated computationally, then synthesized and incorporated into a crosslinked polymer matrix. Experiments revealed three mechanochemically active isomers which differ in …

The synthesis of derivatives of naturally occurring naphthalenes
… may allow the formation of the linear naphthopyran.

Control of mechanochromic reactions in a polymer matrix
… spiropyran (SP) and recently developed naphthopyran (NP), in polymeric matrices. First, the effect of force on the rate constants and activation energies for SP–merocyanine (MC) transition is characterized in bulk polymers. Under different values of a macroscopic tensile stress, the …
