Zinc (Ii) and aiegens: The “clip approach” for a novel fluorophore family. a review [PDF]
, 2021 Aggregation-induced emission (AIE) compounds display a photophysical phenomenon in which the aggregate state exhibits stronger emission than the isolated units. The common term of “AIEgens” was coined to describe compounds undergoing the AIE effect.

Quinoxaline-based azamacrocycles: synthesis, AIE behavior and acidochromism
Organic & Biomolecular ChemistryQuinoxaline-based AIEgens with flexible receptor units were prepared using macrocyclization through the Pd-catalyzed amination reaction. They were then used to prepare AIE-exhibiting test strips for measuring acidity in vapors and aqueous media.

Photo- and halochromism of spiropyran-based main-chain polymers [PDF]
Advanced functional polymeric materials based on spiropyrans (SPs) feature multi-stimuli responsive characteristics, such as a change in color with exposure to light (photochromism) or acids (halochromism).

Quantum Chemical Study of a Dihydroazulene‐Spiropyran Multi‐State Multi‐Functional Molecular Switch
ChemPhotoChem, Volume 8, Issue 9, September 2024.While its UV/vis absorption properties are straightforward to interpret, the DHA‐SP molecular switch turns out to present a complex behavior of its second‐order NLO responses along its successive transformations between its eight state, but TDDFT calculations and the Summation‐Over‐States formalism are efficient tools to explain these and reveal the ...

Molecular aggregation, solvato- and acidochromic properties of symmetrical ketocyanines
Journal of Chemical Sciences, 2013 The absorption and fluorescence spectral characteristics of some symmetrical ketocyanine dyes have been investigated in different solvents of various polarities using steady-state absorption and emission spectroscopic techniques. The absorption spectral features are less sensitive to the solvent characteristics than the corresponding fluorescence ...
