International Classification:

C07D 333/50
C07D 409/14

US Classification:

549 49, 549 59

Abstract:

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.

US Classification:

524 83, 524111

Abstract:

A thermally responsive ink composition consisting of at least one halochromic optical-state change material, at least one base, at least one solvent, and at least one binder material. The pH of the ink composition is such that the halochromic optical-state change material remains in its basic state until it is acted upon by a thermal stimulus. The ink composition is capable of transforming from a first optical state to a second optical state upon a change in pH caused by exposure to a thermal stimulus. A thermally responsive ink composition consisting of at least one quaternary onium salt of an halochromic optical-state change material, at least one solvent, and at least one binder material is also disclosed. Coating compositions prepared using these ink compositions and optical articles comprising these coating compositions are also disclosed.
