ROBUST PHOTOCHROMIC COMPOUNDS WITH SILICON- OR PHOSPHORUS-CONTAINING HETEROCYCLIC RING AND PRODUCTION THEREOF

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.

Synthesis and photoisomerization of diarylcyclobutenes

Symmetrically and unsymmetrically substituted diarylcyclobutenes are synthesized in 20-70% yields from alkyne precursors via cobalt-catalyzed [2+2] cycloadditions. The reactions proceed under mild conditions and provide access to differently substituted diarylethene derivatives. All the diarylcyclobutene products undergo reversible photoisomerization upon irradiation with UV/Vis light. The ring-closed isomers show different thermal stabilities towards reisomerization with half-lives ranging from 9 to 300 hours. Georg Thieme Verlag Stuttgart - New York.
