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
derivatives were readily synthesized from benzoquinone and thiols via an oxidative coupling reaction. The hydroquinone dimers showed strong fluorescence upon excitation at 330 nm, and it was observed that the presence of the sulfanyl groups at the C4 and C4′ positions is important for achieving strong photoluminescence. The tetrapotassium salts of the hydroquinone dimers also showed good water solubility
