Porous organic networks are of great fundamental and technological interest. Here, the authors synthesize a three-dimensional porous organic network with high specific surface area via a solid-state explosive reaction of hexaethynyl triptycene single crystals containing primer molecules.
The activation of cleavable organometallic dimers upon exposure to ultraviolet radiation allows air-stable n-type doping of organic materials with electron affinity lower than the expected thermodynamic reducing strength of the dimers.
Flexible batteries have been used to power wearable smart electronics and implantable medical devices. Here, the authors report a carbon-rich flexible hydrogen substituted graphdiyne electrode exhibiting superior electrochemical performance in lithium and sodium ion batteries.
Sodium-ion batteries are a cost-effective alternative to lithium-ion for large-scale energy storage. Here Bao et al. develop a cathode based on biomass-derived ionic crystals that enables a four-sodium ion storage mechanism leading to exceptionally high specific capacity and energy density.
Traditional approaches used in the pharmaceutical industry are not precise or versatile enough for customized medicine formulation and manufacture. Here the authors produce a method to form coatings, with accurate dosages, as well as a means of closely controlling dissolution kinetics.
Nanostructured films of organic semiconductors are now shown to enhance the Raman signal of probe molecules, paving the way to the realization of substrates for Raman spectroscopy with molecular selectivity.
Computer networks, trained with data from delayed-fluorescence materials that have been successfully used in organic light-emitting diodes, facilitate the high-speed prediction of good emitters for display and lighting applications.
Organic photovoltaics are on the verge of revolutionizing building-integrated photovoltaics. However, for other applications, several basic open scientific questions need answering to, in particular, further improve energy-conversion efficiency and lifetime.
