Solvatochromism in Solvent Mixtures: A Practical Solution for a Complex Problem
LiquidsMany reactions are carried out in solvent mixtures, mainly because of practical reasons. For example, E2 eliminations are favored over SN2 substitutions in aqueous organic solvents because the bases are desolvated.

Spiropyran polymeric microcapillary coatings for photodetection of solvent polarity [PDF]
, 2013 Fused silica micro-capillaries were functionalised with spiropyran-polymer brushes using surface-initiated ring-opening metathesis polymerisation. Based on the inherited spiropyran properties, the functionalised capillaries were successfully used to ...

Accessing Sn≥2 States of a TADF Emitter by Femtosecond NIR Spectroscopy
Chemistry – A European Journal, EarlyView.The depicted thermally activated delayed fluorescence (TADF) emitter was studied by femtosecond near‐infrared (NIR) spectroscopy. A prominent NIR transition was shown to be strongly solvent‐dependent, with implication for intersystem crossing in the compound.

Bright Solvatochromic Fluorophores With Dual Emission Enabled by a Donor‐Engineering Strategy
Chemistry – A European Journal, EarlyView.We screened tertiary amines for installation on the donor unit of highly emissive donor–acceptor‐type solvatochromic fluorophores based on a 9,9‐dimethyl‐2‐phenyl‐9H‐fluorene scaffold, with the aim of enabling two bright emissive states to coexist. As a result, the azetidine derivative [4] and the azepane derivative [7] exhibited clear dual emission ...
