Design and synthesis of an o-hydroxyphenyl-containing spiropyran thermochromic colorant.
نویسندگان
چکیده
An o-hydroxyphenyl-containing spiropyran thermochromic colorant was designed and synthesized. The prepared compound is sensitive to temperature and has a reversible color change with temperature variation. X-ray diffraction analysis and variable-temperature NMR studies suggest that the thermochromism of the compound presumably involved a ring-opening C-O bond cleavage of the spiropyran moiety followed by an intramolecular hydrogen transfer.

Syntheses of quaternary carbon-containing oxazatricycle and spiropyran libraries via multicomponent reactions and their molecular switching properties.
A practical protocol for the preparation of parallel solution-phase libraries of the quaternary carbon-containing oxazatricycles and spiropyrans is reported. Target compounds were obtained in moderate to excellent yields by an Et(3)N-mediated multicomponent reaction from various N-methylisoquinolium or flavylium salts and 4-hydroxycoumarins or dimedone in acetone. Purification of the final prod...
متن کاملDesign and synthesis of a coumarin-based acidichromic colorant.
This paper describes the fine-tuning of the acidichromic properties of a coumarin-containing colorant 1 by incorporation of electron-donating and electron-withdrawing substituents on the coumarin moiety. Colorant 1 can undergo two distinct and reversible color changes under both strongly acidic and basic conditions, but not in the presence of gaseous ammonia. The results indicated that the brom...
