Hydration‐Gated Photoinduced Electron Transfer in BODIPY Dyes
Angewandte Chemie, EarlyView.Hydration switches photoinduced electron transfer (PET) ON in alkoxy‐coordinated BODIPY dyes via specific hydrogen bonding. This gating yields a fluorescence lifetime span of ∼6 ns, enabling fluorescence lifetime imaging microscopy (FLIM) contrast in live cells and organoids. ABSTRACT Fluorescent probes based on photoinduced electron transfer (PET) are

Angewandte Chemie, EarlyView.Here we report two nonalternant polycyclic aromatic hydrocarbons (PAH) (1 and 2), which contain two and four consecutive pentagons, respectively. Under acidic conditions, 1 and 2 dimerize to afford the axially chiral dimers AC1 and AC2. The central azulene moiety in both 2 and AC2 shows an unusually short transannular bond of 1.366 Å.

Advanced Electronic Materials, EarlyView.This study investigates polymer requirements for pairing with high‐efficiency non‐fullerene acceptors (NFA) in organic photovoltaics by comparing three polymer blends across varied phase morphologies. The generation of free charges is driven by fast transport‐assisted charge separation combined with slow intrinsic recombination.

Advanced Energy Materials, EarlyView.Incorporating divinylbenzene into PTAA‐based copolymers induces backbone planarization and promotes polaron delocalization, leading to enhanced doping resilience and stabilized electronic structure. The resulting hole‐transport material, PDVB14, maintains robust performance under high dopant concentrations and prolonged device operation, offering a ...

Angewandte Chemie, EarlyView.The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach

Advanced Energy Materials, EarlyView.A wide process window is essential for the commercialization of perovskite photovoltaics. Here, we demonstrate an amorphous π‐conjugated passivator having an asymmetric mono‐iodine substituent on a carbazole moiety imparts a high dipole moment, desirable molecular energy levels, and high thickness tolerance, thereby enabling a wide process window in ...
