Synthesis of Unsymmetrical 3,7-Bisarylthio-2,8-Dioxydibenzofuran and its Physical Properties
摘要:
Unsymmetrically substituted 8-methoxy-2-hydroxy-3,7-diarylthiodibenzofurans were readily prepared by the intramolecular oxidative condensation reaction of hydroquinone dimers in good yields.
A new dye was developed, the photoluminescence properties of which are controlled by a chemical reaction. The fluorescence properties of 2-sulfanylhydroquinone dimers depend on the number of hydroxyl groups that are acylated. Unprotected or monoacylated 2-sulfanylhydroquinone dimers displayed good fluorescence properties, whereas diacylated and tetraacylated 2-sulfanylhydroquinone dimers showed dramatically
