标题:Photochromic and electrochromic compounds and methods of synthesizing and using same

摘要:This invention relates to novel photochromic and electrochromic monomers and polymers based on 1,2-dithienylcyclopentene derivatives and method of using and synthesizing same. The compounds are reversibly interconvertible between different isomeric forms under suitable photochromic or electrochromic conditions. The electrochromic conversion may be catalytic. The application also relates to ultra-high density homopolymers prepared using ring-opening methathesis polymerization (ROMP) where the central ring of the 1,2-bis(3-thienyl)-cyclopentene is incorporated directly into the polymer backbone. The monomer units may be readily functionalized to enable the synthesis of polymers with diverse structural and electronic properties. The compounds have many potential applications including high-density optical information storage systems, photoregulated molecular switches, reversible holographic systems, ophthalmic lenses, actinometry and molecular sensors, photochromic inks, paints and fibers and optoelectronic systems such as optical waveguides, Bragg reflectors and dielectric mirrors.

摘要:The thienylazolylalkoxyethanamines (I) where R1 is a hydrogen atom, a halogen atom or a lower alkyl radical; R2, R3 and R4 represent, independently, a hydrogen atom or a lower alkyl radical; and Az represents a five-member nitrogenated hetercyclic aromatic group, N-methyl-substituted, that contains from one to three nitrogen atoms. They have analgesic activity in mammals, including humans. The compounds (I) can be obtained, for example, by reaction of a derivative of hydroxy-thienylazol (IV) with a derivative of a suitable N-(ethyl)amine. The compounds (IV) are useful intermediates in the synthesis of the compounds (I). The compounds (I) have an application in human and/or veterinary medicine.
