Characterization of the Pore Environments in Covalent Organic Frameworks by Dynamic Spin Probe Exchange

open access: yesSmall, EarlyView.
Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...

Near‐Theoretical Redox‐Site Utilization and Fast Zn2+ Storage in a Polyimide‐CNT Cathode

open access: yesSmall, EarlyView.
A CNT‐integrated PTO‐based π‐conjugated polyimide cathode achieves near‐theoretical redox‐site utilization, ultrafast Zn2+ storage up to 20 A g−1, and exceptional cycling stability over 10 000 cycles in aqueous zinc‐ion batteries. ABSTRACT Achieving high utilization efficiency together with fast electrochemical transport remains a central challenge for

Seeded Growth of Plasmonic Core‐Shell NU‐1000 NanoMOFs With Intracellular Optical Readout

open access: yesSmall, EarlyView.
Seed‐mediated growth yields plasmonic core‐shell nanocomposites by encapsulating gold nanoparticles within NU‐1000 nanoMOFs, preserving morphology and optical response. The materials exhibit tunable photoluminescence quenching, efficient photothermal heating, and SERS activity.

A Triangulenum‐Based Biosensor Platform for Mapping Kinase Activity in T Cells

open access: yesSmall, EarlyView.
Novel peptide biosensors based on long‐lifetime triangulenium dyes are developed for the real‐time, non‐invasive mapping of Akt1 and Src kinase activities in living cells. Utilizing FLIM microscopy, these highly specific, biocompatible probes overcome cellular autofluorescence.
