Facile Synthesis and Chiral Separation of Chiral Mesoporous Silica Microspheres

Supramolecular chiral transcription and recognition by mesoporous silica prepared by chiral imprinting of a helical micelle.

Let's twist again: The chirality of a helical propeller-like micelle has been memorized by functional groups on the mesopore surface of chiral mesoporous silicas. Such imprinted supramolecular chirality can be transcripted to poly(propiolic acid) sodium salt and tetraphenylporphine tetrasulfonic acid (see picture), and recognized by B-DNA.

Facile synthesis of monodisperse microspheres and gigantic hollow shells of mesoporous silica in mixed water-ethanol solvents.

Mesoporous silica materials with a variety of morphologies, such as monodisperse microspheres, gigantic hollow structures comprising a thin shell with a hole, and gigantic hollow structures consisting of an outer thin shell and an inner layer composed of many small spheres, have been readily synthesized in mixed water-ethanol solvents at room temperature using cetyltrimethylammonium bromide (CT...

Facile synthesis of copper(II) immobilized on magnetic mesoporous silica microspheres for selective enrichment of peptides for mass spectrometry analysis.

Bottom-up synthesis of chiral covalent organic frameworks and their bound capillaries for chiral separation

Covalent organic frameworks (COFs) are a novel class of porous materials, and offer great potential for various applications. However, the applications of COFs in chiral separation and chiral catalysis are largely underexplored due to the very limited chiral COFs available and their challenging synthesis. Here we show a bottom-up strategy to construct chiral COFs and an in situ growth approach ...

Facile synthesis of highly ordered mesoporous silver using cubic mesoporous silica template with controlled surface hydrophobicityw

Recently, there has been great interest in the synthesis and application of various kinds of nanostructured noble metals such as platinum, gold and silver. Nanostructured silvers have been widely investigated as antimicrobial materials, bio-sensors, catalysts, and advanced materials exhibiting surface plasmon resonance and surface enhanced Raman scattering. All this research is mainly based on ...
