Both ternary copolymerization and ternary blending are effective methods to fine‐tune polymer structure and manipulate thin‐film morphology to improve device performance. In this work, three D‐A‐A‐A (D: donor, A: acceptor) terpolymer donors (FY1, FY2, and FY3) are synthesized by introducing BDD (1,3‐bis(2‐ethylhexyl)‐5,7‐di(thiophen‐2‐yl)benzo[1,2‐c:4,5‐c']dithiophene‐4,8‐dione) units into the D–A...
The shape and morphology modulations of covalent organic frameworks (COFs) are both difficult, but are of significance to tackle to realize high‐performance and practical applications. Here, a two‐step method is reported that separates the phase separation and crystallization processes for the shape‐controlled synthesis of COFs. The insight into the polymerization‐induced phase separation (PIPS) allows...
Proton electrochemistry is promising for developing post‐lithium energy storage devices with high capacity and rate capability. However, some electrode materials are vulnerable because of the co‐intercalation of free water molecules in traditional acid electrolytes, resulting in rapid capacity fading. Here, the authors report a molecular crowding electrolyte with the usage of poly(ethylene glycol)...
Rechargeable aqueous proton batteries are promising competitors for the next generation of energy storage systems with the fast diffusion kinetics and wide availability of protons. However, poor cycling stability is a big challenge for proton batteries due to the attachment of water molecules to the electrode surface in acid electrolytes. Here, a hydrogen‐bond disrupting electrolyte strategy to boost...
In article number 1802709, Jean‐Philippe Pellois, Hong‐Cai Zhou, and co‐workers uncover a series of metal‐organic cages as novel and superior cargo delivery scaffolds that target subcellular compartments, such as the nucleus, cytoplasm, and membrane, within a living cell. Through manipulation of the overall charge and surface affinity of the cages, the “nano‐bio” interactions between several cellular...
Understanding the key factors for successful subcellular compartment targeting for cargo delivery systems is of great interest in a variety of fields such as bionanotechnology, cell biology, and nanotherapies. However, the fundamental basis for intracellular transportation with these systems has thus far rarely been discussed. As a cargo vector, porous coordination cages (PCCs) have great potential...
