2-{4-[5-(3-Pyridyl)-2H-tetrazol-2-ylmethyl]phenyl}benzonitrile

Acta Crystallographica Section E, 2008
In the title compound, C20H14N6, there are two molecules with similar conformations in the asymmetric unit. The pyridine and tetrazole rings are nearly coplanar; they are twisted from each other by dihedral angles of only 8.7 (2) and 7.4 (2)&#

High‐Performance Air‐Stable Polymer Monolayer Transistors for Monolithic 3D CMOS logics

Advanced Materials, EarlyView.
A fibrillar polymer monolayer with a self‐confinement effect is demonstrated, in which aligned chains parallel the nanofiber axis. Employing a top‐gate CYTOP dielectric, this monolayer transistor achieves high mobility (7.12 cm2 V−1 s−1) and exceptional stability over 1260 days in air.

Heptazine‐Assisted Multi‐Resonance TADF Emitters With Fast Reverse Intersystem Crossing for Efficient Solution‐Processed OLEDs

Advanced Materials, EarlyView.
Heptazine‐assisted MR‐TADF emitters enable narrowband yellow emission with high efficiency at high luminance in solution‐processed OLEDs. In doped films, HAP‐3CzBN achieves a record‐fast kRISC of 1.19 × 106 s−1. The optimized HAP‐3CzBN devices deliver 15.5% EQEmax with negligible roll‐off at 1000 cd m−2, 11.2% at 10,000 cd m−2, and a benchmark 20.3 ...

Time dependent dihedral angle oscillations of the spike protein of SARS-CoV-2 reveal favored frequencies of dihedral angle rotations

Scientific Reports
The spike protein of SARS-CoV-2 is critical to viral infection of human host cells which ultimately results in COVID-19. In this study we analyzed the behavior of dihedral angles (phi and psi) of the wild-type spike protein over time from molecular ...

Dihedral angles and orthogonal polyhedra

, 2013
Consider an orthogonal polyhedron, i.e., a polyhedron where (at least after a suitable rotation) all faces are perpendicular to a coordinate axis, and hence all edges are parallel to a coordinate axis. Clearly, any facial angle and any dihedral angle is a multiple of $ /2$. In this note we explore the converse: if the facial and/or dihedral angles are

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

Advanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

Bay‐functionalized [7]Helicene Bilayer Nanographenes

Advanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...
