Self‐assembled Helical Tetramer Stack of Terrylene Bisimide in Solution and Crystalline State
Angewandte Chemie, EarlyView.A TBI with sterically demanding imide substituents self‐assembles in solution into a defined helical tetramer π‐stack. Both the monomer and the tetramer can form complexes with polycyclic aromatic guest molecules, resulting in the formation of tri‐ or hexalayer in solution and in the crystalline solid state.

Advanced Energy Materials, EarlyView.Fluorinated tetraphenylethene (TPE) derivatives were developed as interfacial layers for perovskite solar cells. The optimized TFP‐TPE enhances interfacial compatibility, suppresses molecular aggregation, and improves charge extraction. Devices incorporating TFP‐TPE achieved a record efficiency of 25.29% and outstanding stability under humidity and ...

Chiral Heptagon‐Embedded Double [6]Helicenes via Scholl Reaction
Angewandte Chemie, EarlyView.One bond makes the difference–two chiral and twisted polycyclic aromatic hydrocarbons (PAHs) show different emission behavior. The more flexible one (top) shows a double emission with one having a large anti‐Stokes shift. The two peaks are assigned to different conformers of one and the same compound.

Data‐Driven Review and Machine Learning Prediction of Diamond Vacancy Center Synthesis
Advanced Intelligent Systems, EarlyView.A machine learning framework is applied to photoluminescence spectra to extract linewidths and uncover how NV, SiV, GeV, and SnV centers evolve with growth and processing conditions. Unified normalization and k‐fold validation reveal cross‐method trends and enable rapid prediction of defect size and fabrication parameters, offering a data‐driven route ...

Journal of Marine Science and Engineering, 2015 Barrier islands of Northwest Florida were heavily oiled during the Deepwater Horizon spill, but less is known about the impacts to the shorelines of the associated estuaries. Shoreline sediment oiling was investigated at 18 sites within the Pensacola Bay,
