A Metal—Organic Framework Material that Functions as an Enantioselective Catalyst for Olefin Epoxidation.

Abstract

Enantioselective syntheses O 0031A Metal-Organic Framework Material that Functions as an Enantioselective Catalyst for Olefin Epoxidation. -A novel, microporous metal-organic framework compound containing chiral Mn(salen) struts appears to be an efficient and reusable asymmetric catalyst for the olefin epoxidation. In comparison to the free Jacobsen-type catalyst, framework immobilization confers multiple advantages such as higher stability, easier separation, recyclability, and substrate size selectivity. -(CHO, S.-H.; MA, B.; NGUYEN, S.

Engineering chiral porous metal-organic frameworks for enantioselective adsorption and separation

“…In particular, chiral MOFs are highly promising for the separation of enantiomers and for chiral catalysis, as a result of their high porosity, functional diversity, flexibility and size and shape selectivity, surpassing traditional inorganic and organic porous materials [16][17][18][19][20] . Chiral MOF catalysts with uniform active sites for enantioselective reactions have been developed based on functionalized chiral molecular (pre)catalysts [21][22][23][24][25][26][27][28][29][30] . In a handful of latest studies, the resolution of enantiomers (racemic alcohols and sulphoxides) with chiral MOFs via chromatography [31][32][33][34] , crystallization [35][36][37][38][39][40] and membrane 41,42 has been reported, but only few exhibit good chiral separation performance.…”

Synthesis, Crystal Structure, and Electroconducting Properties of a 1D Mixed-Valence Cu(I)–Cu(II) Coordination Polymer with a Dicyclohexyl Dithiocarbamate Ligand

“…Crystal engineering of coordination polymers attracts increased attention in the field of materials science because of their exceptional chemical and physical properties, such as magnetic [1][2][3] and conductive [4][5][6][7][8][9][10][11][12][13][14][15][16][17], dielectric [18][19][20], gas-absorbing [21][22][23], and catalytic properties [24][25][26][27]. In particular, mixed-valence coordination polymers have attracted considerable interest as a new class of functional materials because of their unique infinite structures and electronic states formed by the combination of different metal ions having versatile coordination architectures and a variety of organic bridging ligands.…”

Dye-sensitized Solar Cells with New One-Dimensional Halide-Bridged Cu(I)–Ni(II) Heterometal Coordination Polymers Containing Hexamethylene Dithiocarbamate Ligand

“…Crystal engineering of coordination polymers is one of the most attractive subjects in the field of materials science because of the polymers' versatile chemical and physical properties such as magnetic [1][2][3] and conductive [4][5][6][7][8][9][10][11][12][13][14], dielectric [15][16][17], gas-absorbing [18][19][20], and catalytic properties [21][22][23][24]. One of the most attractive areas in this field is the synthesis of conductive coordination polymers, in terms of both fundamental topics such as d-π systems [25] and applications to novel optoelectronic devices such as electroluminescent (EL) devices [26], field-effect transistors (FETs), and solar cells [27].…”
