Microenvironmental Tuning in Isostructural Conjugated Metal–Organic Frameworks for Superior Photocatalytic H2O2 Generation

open access: yesAngewandte Chemie, EarlyView.
Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

A Mechanical sp2‐Jail for C60 Fullerene

open access: yesAngewandte Chemie, EarlyView.
A rigid bisporphyrin receptor with an exceptionally compact 3D cavity functions as a molecular “mechanical jail”, tightly enclosing C60 fullerene. Near‐perfect shape complementarity affords ultrahigh binding affinity while imposing a large kinetic barrier for guest exchange, rendering encapsulation effectively irreversible under ambient conditions ...

Volatile Memristive Devices With Tunable Temporal Dynamics For Event‐Based Sensing

open access: yesAdvanced Materials, EarlyView.
Tunable volatile memristive devices can serve various neural‐inspired tasks that require different time windows of information retention. The ionic‐based volatility of the presented Pt/a‐STO/TaOx/Ta device stack can be reproducibly and controllably tuned in multiple ways.
