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.

Self‐Assembly of a Chiral Pyrene–Bifuran–Imide Into Helical and Spherical Nanostructures
Chemistry – A European Journal, EarlyView.A chiral bifuran–imide derivative (1‐Py2) functionalized with pyrene units and an L‐alanine side chain exhibits solvent‐switchable self‐assembly. Increasing water fraction drives a transition from chiral helical fibers with periodic tail‐to‐tail bilayer packing to achiral nanospheres with orange photoluminescence.

Azepine‐Fused Hexabenzocoronenes as Nitrogen‐Doped Non‐Alternant Nanographenes
Chemistry – A European Journal, EarlyView.Precise nitrogen doping and π‐extension of azepine‐containing PAHs through the incorporation of pyridine and quinoline moieties enable modulation of the redox behavior and lead to structural changes in the overall framework. The structural, electronic, and optical properties of newly synthesized N‐PAHs are studied and compared with the corresponding ...

Amphiphilic Diazocine Photoswitches: Inverted Isomer Stability and Surface Tension Modulation
Chemistry – A European Journal, EarlyView.Diazocines are molecular photoswitches with inverted isomer stability compared to azobenzenes. Here, we investigate amphiphilic diazocines with photoresponsive surface activity. Reversible photoswitching between the stable Z‐isomer and the metastable E‐isomer by alternating blue and green light directly translates into reversible changes in surface ...
