3 results about "Tetrathiafulvalene" patented technology

This invention relates to the field of catalyst technology, and particularly to a method for preparing and applying a self-photosensitive organic molecular catalyst. The method for preparing the self-photosensitive organic molecular catalyst includes the following steps: deprotonating tetrathione with a non-nucleophilic strong base to obtain deprotonated tetrathione; subjecting the deprotonated tetrathione to a nucleophilic substitution reaction to obtain a monotin-substituted tetrathione; subjecting the monotin-substituted tetrathione to a Stille coupling reaction with 5-bromo-isophthalaldehyde to obtain a tetrathione derivative containing multiple aldehyde groups; and reacting the tetrathione derivative containing multiple aldehyde groups with a polyamine via a Schiff base reaction to obtain the self-photosensitive organic molecular catalyst. The self-photosensitive organic molecular catalyst of this invention achieves a synergistic reaction of CO2 reduction and organic molecule oxidation without the need for additional photosensitizers and sacrificial agents.

This invention provides a tetrathiofulvalene tetrabenzaldehyde Schiff base cage compound, the molecular formula of which is C2. 126 H 108 N 16 S 12 The molecular weight is 2231.08, and the unit cell parameters are: a=17.0810(12)Å, b=19.3138(13)Å, c=22.0054(4)Å; α=104.811(2)°, β=101.466(2)°, γ=101.348(2)°, V=6639.3(8)Å. 3 The compound has a Z=2 crystal, space group P-1, and belongs to the triclinic crystal system. It exhibits a wide ultraviolet transmission cutoff edge above 400 nm and a significant near-infrared absorption rate. Near-infrared photothermal conversion performance tests show that the crystal can stably reach above 160°C in 40 seconds during 10 light-cooling cycles, demonstrating excellent photothermal conversion performance. This crystal is obtained through a liquid-phase diffusion method, where it is allowed to diffuse freely by layering and allowing it to stand still. This method offers advantages such as simple operation, the use of common organic raw materials, a short growth cycle, and stable physicochemical properties, making it suitable for various photothermal conversion materials.
