A Neutral “Masked” Diborene and Its Reactivity Toward Metal‐Free Pyridine Homocoupling
Angewandte Chemie, EarlyView.An unprecedented neutral “masked” diborene, formed via intramolecular arene dearomatization of an N‐heterocyclic imine‐supported free diborene, can be photochemically released to regenerate the highly reactive triplet diborene intermediate. Computational analysis elucidates the bonding situation of the hitherto elusive free diborene species, and the ...

Diisopropyl pyrazine-2,5-dicarboxylate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 The mol-ecule of the title compound, C(12)H(16)N(2)O(4), is located on an inversion center. The carboxyl-ate groups are twisted slightly with respect to the pyrazine ring, making a dihedral angle of 6.4 (3)°.

High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks
Advanced Materials, EarlyView.A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

Diethyl pyrazine-2,5-dicarboxylate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 The mol-ecule of the title compound, C(10)H(12)N(2)O(4), is located around an inversion center. The carboxyl-ate groups are twisted slightly with respect to the pyrazine ring, making a dihedral angle of 2.76 (19)°. In the crystal, mol-ecules are stacked along the c axis via weak C-H⋯O hydrogen bonds.

Porous Organic Cages for CO2 Capture and Confined Reduction
Angewandte Chemie, EarlyView.Porous organic cages (POCs) enable the coupling of CO2 capture and conversion through the interplay of molecular structure and solid‐state organization. Beyond intrinsic cavities, packing‐dependent pore accessibility and mass transport govern local CO2 concentration and catalytic performance, linking adsorption to reactivity in integrated capture ...

Methyl pyrazine-2-carboxylate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2009 The title compound, C(6)H(6)N(2)O(2), is approximately planar [r.m.s. deviation = 0.0488 (3) Å]. In the crystal, weak inter-molecular C-H⋯O and C-H⋯N inter-actions join the mol-ecules into an infinite three-dimensional network.
