    摘要: Photochromic and electrochromic hexadiene compounds that are reversibly convertible between ring-open and ring-closed isomeric forms. The conversion between the different isomeric forms may be induced by light or electricity. The compounds may include a charge transfer moiety including electron donor and acceptor groups. The electron donor and acceptor are linearly conjugated in the ring-open form to enable electron transfer but are electrically insulated in the ring-closed form. Photoresponsive compounds may be synthesized by any of several methods disclosed, e.g., by reacting diene precursors with dienophiles in a condensation reaction. The compounds may be utilized in reactivity-gated photochromic or electrochromic applications. Compounds may be used in a method to selectively release a releasable agent, such as a small molecule.

    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.
