    摘要: The invention relates to an optical recording material comprising: a polymeric matrix; a dewarbenzene derivative reactant capable of undergoing isomerization to a benzene product upon triplet excitation, thereby causing a change in optical properties; and a sensitizer capable of absorbing actinic radiation to cause triplet energy transfer to said reactant, wherein the algebraic sum of the excitation energy of said sensitizer and its reduction potential is at least 0.05 eV less than the oxidation potential of said reactant, thereby precluding one-electron oxidation of said reactant. The invention further relates to an optical device comprising regional variations in concentrations of reactants and products produced by triplet chain isomerization, thereby providing a pattern of intelligence.

    摘要: Production of polyenaminonitriles including those which can be cyclized to very stable poly(aminoquinolines) without the evolution of any small molecules and thus in a manner free of volatiles. The polyenaminonitriles are polymers which have desirable dielectric properties, and include those which can be cyclized to poly(aminoquinolines) without the evolution of volatiles to make defect-free films and composites of similar dielectric properties because of this characteristic.
