Protonation‐Induced Electron Density Redistribution Facilitates Aggregation in PNNP Dicopper Hydride Complexes

Chemistry – A European Journal, EarlyView.
Copper(I) hydride complexes often exhibit diverse aggregation behavior that can profoundly influence their structure and reactivity. In this study we use a combined experimental and computational approach to identify key structural an electronic factors that govern aggregation in PNNP dicopperhydride complexes.

Controlling Aggregation‐Induced Emission by Sterics in Nitrogen–Boron–Nitrogen (NBN)‐Doped Tetraphenylethylene‐Like Molecular Propellers

Chemistry – A European Journal, EarlyView.
Nitrogen–boron–nitrogen (NBN)‐substituted molecular propellers are presented as structural framework for aggregation induced emission (AIE) applications. Steric hindrance is revealed to steer maximum‐AIE behavior, leading to refined control over assembly‐induced luminescence.
