摘要:1,1,2,2,3,3,4-Heptafluorocyclopentane Is A New Generation Of Green Solvent. It Was Synthesized By The Liquid-Phase Fluorination Reactions From Hexachlorocyclopentadiene To 1-Chloroheptafluoro-Cyclopentene In The Presence Of Kf In Dmf And By The Vapor-Phase Hydrogenation Reaction From 1-Chloroheptafluorocyclopentene To 1,1,2,2,3,3,4-Heptafluorocyclopentane In The Presence Of Pd-Based Hydrogenation Catalyst. Quantum Chemical Calculations For The Isomers Energies Using Gaussian09 Were Conducted To Verify The Chemical Equilibriums Between Isomers Of Trichloropentafluorocyclopentene Or Dichlorohexafluorocyclopentene In The Fluorination Reactions. Possible Mechanisms For 1,1,2,2,3,3,4-Heptafluorocyclopentane Synthesis Were Proposed. (C) 2015 Elsevier B.V. All Rights Reserved.

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.
