Transformable periodic mesoporous organosilica materials.
The synthesis of novel periodic mesoporous organosilica (PMO) materials incorporating a mixture of functional monomers (cis- and trans-stilbene-based) and structural monomers has been accomplished. EDX analysis of these materials in combination with HAADF imaging of OsO(4)-stained samples reveals a homogeneous distribution of trans-olefin within the co-condensed aromatic organosilica matrix. Oz...
متن کاملVisible-light-harvesting periodic mesoporous organosilica.
Highly ordered periodic mesoporous organosilica synthesized from a newly designed 9(10H)-acridone bridged organosilane precursor exhibited efficient light-harvesting antenna properties for visible light, at wavelengths up to 450 nm.
متن کاملPeriodic Mesoporous Organosilica Nanorice
A periodic mesoporous organosilica (PMO) with nanorice morphology was successfully synthesized by a template assisted sol-gel method using a chain-type precursor. The PMO is composed of D and T sites in the ratio 1:2. The obtained mesoporous nanorice has a surface area of 753 m(2) g(-1), one-dimensional channels, and a narrow pore size distribution centered at 4.3 nm. The nanorice particles hav...
متن کاملUnexpected golden Ullmann reaction catalyzed by Au nanoparticles supported on periodic mesoporous organosilica (PMO).
We demonstrated an unprecedented example of Ullmann homocoupling reaction of aryl iodides over a novel recyclable gold catalyst comprising Au nanoparticles supported on a bifunctional periodic mesoporous organosilica (Au@PMO).
متن کاملPeriodic mesoporous organosilica from zwitterionic precursors.
Mesoporous hybrid silica bearing zwitterionic species were synthesized via template-directed hydrolysis-polycondensation reactions from zwitterionic ammonium sulfonate precursors. The formation of the nanostructured phases involves specific precursor-template interactions. The obtained materials are efficient heterogeneous catalysts in Biginelli reactions.
