Durable Metal‐Organic Frameworks by Covalent Hybridization with Polyurethane and Polyallophanate
Asian Journal of Organic Chemistry, EarlyView.The organic ligands in MOFs were polymerized with diisocyanate, forming polyallophanate and polyurethane networks inside single crystals of MOFs. The hybridization of brittle MOF structure and flexible polyurethane and polyallophanate resulted in highly tough MOF crystals.

Full-dimensional theory of pair-correlated HNCO photofragmentation [PDF]
arXiv, 2017 Full-dimensional semiclassical dynamical calculations are reported for the photofragmentation of isocyanic acid in the S1 state. These calculations, performed for the first time, allow to closely reproduce the key features of high-resolution imaging measurements at photolysis wavelengths of 201 and 210 nm while providing insight into the underlying ...
