Metal-Organic Covalent Network Chemical Vapor Deposition for Gas Separation

The chemical vapor deposition (CVD) polymerization of metalloporphyrin building units is demonstrated to provide an easily up-scalable one-step method toward the deposition of a new class of dense and defect-free metal–organic covalent network (MOCN) layers. The resulting hyper-thin and flexible MOCN layers exhibit outstanding gas-separation performances for multiple gas pairs.United States. Army Research Office.

A synthetic biological quantum optical system

In strong plasmon–exciton coupling, a surface plasmon mode is coupled to an array of localized emitters to yield new hybrid light–matter states (plexcitons), whose properties may in principle be controlled via modification of the arrangement of emitters. We show that plasmon modes are strongly coupled to synthetic light-harvesting maquette proteins, and that the coupling can be controlled via alteration of the protein structure. For maquettes with a single chlorin binding site, the exciton energy (2.06 ± 0.07 eV) is close to the expected energy of the Qy transition. However, for maquettes containing two chlorin binding sites that are collinear in the field direction, an exciton energy of 2.20 ± 0.01 eV is obtained, intermediate between the energies of the Qx and Qy transitions of the chlorin. This observation is attributed to strong coupling of the LSPR to an H-dimer state not observed under weak coupling

A facile one-pot transformation of Baylis-Hillman adducts into unsymmetrical disubstituted maleimide and maleic anhydride frameworks: a facile synthesis of himanimide A

Unsymmetrical, disubstituted maleimide and maleic anhydride frameworks have been accessed from Baylis-Hillman adducts in an operationally simple three-step (Friedel-Crafts reaction, selective hydrolysis, and cyclization), one-pot strategy. This strategy has been successfully extended to the synthesis of a representative bioactive compound, himanimide A
