Title:
ROBUST PHOTOCHROMIC COMPOUNDS WITH SILICON- OR PHOSPHORUS-CONTAINING HETEROCYCLIC RING AND PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/188790
Kind Code:
A1
Abstract:
In one embodiment, provided are a new class of diarylethene-containing photochromic compounds with the incorporation of silicon-or phosphorus-containing heterocycles into the "ethene" part of the diarylethene backbone that has been shown to be capable of displaying tunable, robust and thermally stable photochromic properties. Also provided are methods for synthesizing these compounds, as well as uses of these compounds as these compounds may be used as the photochromic layer in an optical recording material and other optical functioning devices.
