Engineering Bodipy‐Based Metal–Organic Frameworks for Efficient Full‐Spectrum Photocatalysis in Amide Synthesis

open access: yesAngewandte Chemie, EarlyView.
Three highly stable bodipy‐based metal–organic frameworks (BMOFs) were synthesized by treating dicarboxyl‐functionalized bodipy ligands with Zr‐oxo clusters. Featuring the distinct bodipy scaffold in the framework, these BMOFs displayed high reactivity in heterogenous photocatalytic C─H bond activation of N,N‐dimethylanilines to access amides under ...

Fluorinated Functional Units for Li+ Flux Homogenization in Silica Framework‐Based Zwitterionic Single Ion Conductors for Stable Lithium Metal Batteries

open access: yesAdvanced Energy Materials, Volume 15, Issue 21, June 3, 2025.
We engineered a novel SF‐ZSIC electrolyte by co‐grafting fluorinated anionic and zwitterionic monomers onto a robust silica framework. This design forms powerful solvation channels that drive ultra‐stable, excellent‐performance lithium metal batteries (LMBs).

Enhanced and Durable Light‐Driven Hydrogen Evolution by Cobalt‐Based Prussian Blue Analogs in Phospholipid Bilayers

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Light‐driven H2 evolution catalysis is reported for oleylamine‐capped MCo Prussian blue analogs (PBAs, M = Ni, Co, Zn, Cu) within phospholipid bilayers and using a ruthenium‐based amphiphilic photosensitizer. The hydrophobic interactions between the active units bring them in close proximity facilitating catalysis.
