Syntheses and Photochromic Properties of Thiophenophan-1-ene-S,S,S′,S′-tetraoxides

Photochromic thiophenophan-1-ene-S,S,S′,S′-tetraoxides have been synthesized by oxidation of sulfur atoms of thiophenophan-1-enes, and their photochromic properties were studied. The tetraoxides indicated photochromism and the quantum yields for photocyclization reactions became higher than that of...

Description
Summary:Photochromic thiophenophan-1-ene-S,S,S′,S′-tetraoxides have been synthesized by oxidation of sulfur atoms of thiophenophan-1-enes, and their photochromic properties were studied. The tetraoxides indicated photochromism and the quantum yields for photocyclization reactions became higher than that of nonbridged dithienylethene-S,S,S′,S′-tetraoxide due to fixation of conformations.
