Reductive Activation of White Phosphorus to [P4]2–, [P2]2–, and a Formal P2– Radical by Rare‐Earth Dinitrogen Complexes

Angewandte Chemie, EarlyView.
Masked divalent yttrium and gadolinium dinitrogen complexes mediate the fragmentation of white phosphorus, converting P4 into discrete dimetallic complexes of [P4]2– and [P2]2– ligands, and an unprecedented monatomic P2– radical ligand. Structural, spectroscopic, magnetic, and DFT studies reveal insight into the bonding between these unusual Pn units ...

Functional and Network PHAs via Stereoselective Polymerization and Tailored Post‐Transformation

Angewandte Chemie, EarlyView.
Catalyst‐controlled stereoselective (co)polymerization of functionalized lactones produces vinyl‐, allyl‐, and propargyl‐functionalized PHAs with high syndiotacticity and a broad applicable temperature window, which can be further transformed into crosslinked PHA thermosets, elastic supramolecular networks, and functional grafts.

Neodymium‐Doped Nanocrystals for Sensing Cellular Temperature at the Nanoscale

Advanced Optical Materials, EarlyView.
Neodymium‐doped NaYF4 nanocrystals are engineered as bright, biocompatible nanothermometers for intracellular temperature mapping. Their ratiometric near‐infrared emission enables highly sensitive, nanoscale thermal readouts in living cells. Combined with gold nanostars for photothermal therapy, they reveal pronounced subcellular heating heterogeneity ...

Red Fluorescent Protein‐Metal Organic Framework Hybrids for Lighting Applications

Advanced Optical Materials, EarlyView.
We demonstrate the encapsulation in a metal‐organic framework (MOF) of two red fluorescent proteins, DsRed and mCherry. The materials conserve all spectroscopical and structural properties of the underlying components, which allows for their implementation as color down‐converting materials in bio‐hybrid light‐emitting diodes, which exhibit average 3 ...
