COMPOSITION, PHOTOELECTRIC CONVERSION ELEMENT, AND IMAGING DEVICE

A composition contains a naphthalocyanine derivative represented by the following formula: where R1 to R8 are independently an alkyl group and R9 to R12 are independently an aryl group, and at least one hydrogen atom in at least one selected from the group consisting of R9, R10, R11, and R12 is substituted by an electron-withdrawing group.

Metal-free hydrogen evolution cross-coupling enabled by synergistic photoredox and polarity reversal catalysis

A synergistic combination of photoredox and polarity reversal catalysis enabled a hydrogen evolution cross-coupling of silanes with H2O, alcohols, phenols, and silanols, which afforded the corresponding silanols, monosilyl ethers, and disilyl ethers, respectively, in moderate to excellent yields. The dehydrogenative cross-coupling of Si-H and O-H proceeded smoothly with broad substrate scope and good functional group compatibility in the presence of only an organophotocatalyst 4-CzIPN and a thiol HAT catalyst, without the requirement of any metals, external oxidants and proton reductants, which is distinct from the previously reported photocatalytic hydrogen evolution cross-coupling reactions where a proton reduction cocatalyst such as a cobalt complex is generally required. Mechanistically, a silyl cation intermediate is generated to facilitate the cross-coupling reaction, which therefore represents an unprecedented approach for the generation of silyl cationviavisible-light photoredox catalysis.

Photocatalyzed cross-dehydrogenative coupling of silanes with alcohols and water

An efficient method for the dehydrogenative coupling of silanes with alcohols under photocatalysis was developed. The reaction proceeded in the presence of Ru(bpy)3Cl2(0.5 mol%) under visible light irradiation in acetonitrile at room temperature. The developed methodology was also applicable for the synthesis of silanols using water as a coupling partner.

Highly Selective Hydroxylation and Alkoxylation of Silanes: One-Pot Silane Oxidation and Reduction of Aldehydes/Ketones

An efficient chemoselective iridium-catalyzed method for the hydroxylation and alkoxylation of organosilanes to generate hydrogen gas and silanols or silyl ethers was developed. A variety of sterically hindered silanes with alkyl, aryl, and ether groups were tolerated. Furthermore, this atom-economical catalytic protocol can be used for the synthesis of silanediols and silanetriols. A one-pot silane oxidation and chemoselective reduction of aldehydes/ketones was also realized.

Metal-free visible-light-mediated aerobic oxidation of silanes to silanols

Oxidation of silanes into silanols using water/air has attracted considerable attention. The known methods with no exception required a metal catalyst. Herein we report the first metal-free method: 2 mol% Rose Bengal as the catalyst, air (O2) as the oxidant, water as the additive and under visible light irradiation. While this method produces various silanols in a simple, cost-effective, efficient (92%–99% yields) and scalable fashion, its reaction mechanism is very different than the reported ones associated with metal catalysis.

A method for catalytic synthesis of silanol

The invention discloses a method for catalytically synthesizing silanol and relates to the fields of organic chemicals and fine chemicals. The method is essentially a transition metal catalyzed organic synthesis reaction. In the method, the raw materials comprise organosilane and a clean oxidant, a used catalyst is inexpensive copper salt, the raw material is heated and stirred to react without a solvent so as to rapidly produce silanol at a moderate temperature. By adopting the method, the reaction time is 3-12 hours. The mole ratio of the organosilane to the clean oxidant is 1:(1-5), the copper salt as the catalyst accounts for 1-10mol% of the mole number of the organosilane, the raw materials react at a temperature of 50-80 DEG C, and then the silanol can be greatly yielded after simple posttreatment. The oxidant used in the method is safe and nontoxic, and the catalyst used in the method is cheap and easily available. The method disclosed by the invention is a very simple and practical method for synthesizing silanol.

Molecularly designed nanoparticles by dispersion of self-assembled organosiloxane-based mesophases

The design of siloxane-based nanoparticles is important for many applications. Here we show a novel approach to form core-shell silica nanoparticles of a few nanometers in size through the principle of dispersion of ordered mesostructures into single nanocomponents . Self-assembled siloxane-organic hybrids derived from amphiphilic alkyl-oligosiloxanes were postsynthetically dispersed in organic solvent to yield uniform nanoparticles consisting of dense lipophilic shells and hydrophilic siloxane cores. Insitu encapsulation of fluorescent dyes into the nanoparticles demonstrated their ability to function as nanocarriers. Self-assembled hybrid nanoparticles: A new type of oligosiloxane precursor self-assembles into reverse-micellar mesostructures, which can be transformed to nanoparticles with a siloxane core and an organic shell by dispersion in nonpolar organic solvents.
