Highly Selective Adsorption of Fluorinated Gases by Porous Organic Cages – Effects of Fluorinated Side‐Chains

open access: yesAdvanced Materials, EarlyView.
A systematic study of a series of porous organic cages with perfluorinated alkyl side‐chains of different lengths is presented. The structure‐property relationship of the various cages on gas sorption of highly potent greenhouse gases, such as perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) is investigated.

Enhanced Selectivity of Chalcogen Bonding over Halogen Bonding Catalyzed C‐glycosylation Through Differentiated Intermediate Activation

open access: yesAngewandte Chemie, EarlyView.
By harnessing chalcogen bonding (ChB) catalysis, an exclusive access into a highly stereoselective strain‐release C‐glycosylation pathway was discovered. This was surprisingly not replicable by the conceptually similar halogen bonding (XB) catalysis.

Utilizing Proteolytic‐Resistant Nano‐Short Peptide Based on Naphthyl Tail‐Anchored to Combat Bacterial Infections

open access: yesAdvanced Science, EarlyView.
Antimicrobial peptides (AMPs) show potential as alternatives to antibiotics for bacterial infections; however, their susceptibility to proteases limits wider application. In this study, N4 nanofibers are constructed by integrating anti‐enzymolysis motif into the self‐assembly system triggered by naphthyl‐anchored.

Ionic Covalent Organic Framework Membranes for Rapid Moisture‐Driven Actuation and Sensing

open access: yesAngewandte Chemie, EarlyView.
This study introduces an ionic covalent organic framework membrane that responds to humidity within1 s, enabling reversible bending, sensing, and switching behaviors. The integration of guanidinium linkers enhances water affinity and structural adaptability. With high mechanical resilience and environmental responsiveness, the membrane offers promising

Doping of Graphene Nanoribbons via Functional Group Edge Modification

open access: yes, 2017
We report on the on-surface synthesis of 7 armchair graphene nanoribbons (7-AGNRs) substituted with nitrile (CN) functional groups. The CN groups are attached to the GNR backbone by modifying the 7-AGNR precursor.

Abrupt and Reversible Stretching in an Azobenzene Single Crystal via Thermal Phase Transition

open access: yesAdvanced Science, EarlyView.
Crystals of azobenzene compounds exhibit abrupt and reversible stretching and shrinking in response to thermal and photo stimulation. The single‐crystal‐to‐single‐crystal phase transition between two polymorphs involving reorientation of CH–π hydrogen interactions are demonstrated. Furthermore, the abrupt photoinduced stretching of the crystals is used
