Structure–property relationships in aromatic thioethers featuring aggregation-induced emission: solid-state structures and theoretical analysis

Abstract

The evolution of the fluorescence quantum yields was correlated with the increase of C–H⋯π and the decrease of π⋯π interactions in the solid state.

Photo-switching and -cyclisation of hydrogen bonded liquid crystals based on resveratrol

“…22 This methodology allowed us recently to rationalize the AIE-behaviour of a series of aromatic thioethers. 23 Details on the methodology are given in the ESI. ‡ A reference molecule in the crystalline packing was defined (as provided by CrystalExplorer) and molecular pairs (= structure determinants) with surrounding molecules were analysed with respect to their intermolecular interactions.…”

Alkyl‐Alkyl Interactions in the Periphery of Supramolecular Entities: From the Evaluation of Weak Forces to Applications

“…Here, a reference molecule in the crystalline packing was defined and then pairs with surrounding molecules were analyzed with respect to their intermolecular interactions. Our first study aiming to explain the aggregation induced emission (AIE) behavior of liquid crystalline materials, revealed that the fluorescence behavior is controlled by dispersions interactions (Figure ) . The significantly enhancement of the fluorescence quantum yield was related to the significant increase of C−H⋯π and the decrease of π⋯π interactions in the solid state.…”

Mesogens with Aggregation-Induced Emission Formed by Hydrogen Bonding

“…45 This methodology was recently applied by our group to quantify the noncovalent interactions in a series of aromatic thioethers featuring AIE and to rationalize their photophysical behavior. 46 Details on the methodology are given in the Supporting Information.…”

“…In order to quantify the noncovalent interactions occurring in our system and proving that it is truly driven by hydrogen bonding, we analyzed the crystal structure of m N m P-(St) 2 by employing intermolecular perturbation theory developed by Turner et al, implemented in the CrystalExplorer software . This methodology was recently applied by our group to quantify the noncovalent interactions in a series of aromatic thioethers featuring AIE and to rationalize their photophysical behavior . Details on the methodology are given in the Supporting Information.…”
