Opening a bandgap in bilayer graphene typically requires either structural modification or continuous external electric fields, while twisted bilayer graphene configurations remain largely gapless without additional perturbation. Here, we demonstrate bandgap opening of up to 50 meV in structurally intact bilayer graphene by in-plane strain fields imposed by an interfaced porous organic 2D crystal…

Radiation-based energy-saving strategies, including solar heating (SH) and radiative cooling (RC), have emerged as sustainable solutions that operate without an external energy input. SH relies on broadband solar absorbers to capture solar radiation, whereas RC employs selective emitters with high solar reflectance and strong thermal emissivity in the atmospheric transparent window regime. Despit…

Fluorination of building block molecules is one of the effective engineering approaches to modulate molecular assembly in crystalline organic materials. Herein, we constructed a hydrogen-bonded organic framework (HOF) from a tetraphenylethene derivative, F-CBPE, possessing 3,5-difluoro-4-carboxyphenyl groups. The introduction of fluorine atoms in ortho-positions of the carboxy group makes the con…

With the popularization of 5G communication technology and the rapid development of electronic devices, electromagnetic interference (EMI) shielding materials are widely concerned. Conductive polymeric composites (CPCs) are usually used in EMI shielding due to their flexibility, corrosion resistance, processability and biocompatibility compared to metal-based EMI shielding materials. The demand f…

Achieving simultaneously high efficiency and thermal stability in perovskite quantum dot light-emitting diodes (PeLEDs) requires fundamentally rethinking surface ligand design.
