Chemistry – A European Journal, EarlyView.Two families of bTurea‐derived biradicals, bcTmols and bcTCOOKs, were prepared as polarizing agents for dynamic nuclear polarization (DNP)‐enhanced NMR through short and efficient synthetic routes. The best‐performing biradical, bcTCOOK‐M2, containing two methyl groups on the urea bridge, provided signal enhancements of up to ∼220 at 14.1 T and 100 K ...

Chemistry – A European Journal, EarlyView.This study investigates how molecular topology influences the photophysical properties of star‐shaped, threefold‐symmetric triphenylamine (TPA) derivatives functionalized with three BODIPY or SubPc units. Their absorption spectra exhibit minimal solvatochromism, whereas their fluorescence intensity is strongly dependent on solvent polarity.

Long Fluorescence Lifetime Molecular Rotors Based on the 4,4‐Dicyano‐BODIPY Core
Chemistry – A European Journal, EarlyView.Substituting fluorine with cyano groups in BODIPY‐based fluorescent molecular rotors yields viscosity‐sensitive dyes with significantly enhanced fluorescence lifetimes that can be used for viscosity mapping in living cells using FLIM microscopy. ABSTRACT Environmentally sensitive fluorescent probes with extended emission lifetimes are highly valuable ...

Structure–Activity Relationships in Methyl‐Driven Overhauser Effect DNP
Chemistry – A European Journal, EarlyView.Dynamic nuclear polarization (DNP) was investigated in a wide array of methyl‐containing Blatter radicals to identify design principles for the synthesis of an Overhauser DNP polarizing agent. Fourteen different radicals were synthesized, which revealed that only radicals possessing sterically unhindered methyl groups in sites of high spin density were
