Controlling Aggregation-Induced Emission by Sterics in Nitrogen-Boron-Nitrogen (NBN)-Doped Tetraphenylethylene-Like Molecular Propellers. [PDF]
ChemistryNitrogen–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.

SOLVATOCROMISMO E AS ESCALAS EMPÍRICAS DE POLARIDADE DO SOLVENTE: UMA REVISÃO [PDF]
Química Nova, 2023 The term solvatochromism is used to describe the changes in the optical properties of a dye molecule by influence of the solvent characteristics. Solvatochromic shifts are governed by intermolecular interactions between solute-solvent that can be either ...

Solvatochromic covalent organic frameworks [PDF]
Nature Communications, 2018 AbstractCovalent organic frameworks (COFs) are an emerging class of highly tuneable crystalline, porous materials. Here we report the first COFs that change their electronic structure reversibly depending on the surrounding atmosphere. These COFs can act as solid-state supramolecular solvatochromic sensors that show a strong colour change when exposed ...
