DOI: 10.1016/j.dyepig.2021.109475
Abstract: Abstract Phenylmethylidene-bis(pyrrolo[2,3-b]quinoxaline) derivative (1) was synthesized by the reaction between the 3-thiobenzoylpyrrolo[2,3-b]quinoxaline (SPQ) and a secondary amine or NaOH in DMF solution. The obtained compound was characterized by single crystal X-ray diffraction, which indicated the… read more here.

DOI: 10.1039/d1dt03327a
Abstract: The combination of redox-active metals with redox-active ligands can lead to interesting charge transfer behaviours, including valence tautomerism and solvatochromism. With the aim of investigating a relatively underexplored redox-active metal/redox-active ligand combination, complexes [CoII(acac)2(X-BIAN)] (acac-… read more here.

DOI: 10.1039/d3cc00545c
Abstract: It is rare for one fluorophore scaffold to harbor both positive and negative solvatochromism. Herein, we tailor chalcone analogues to achieve both positive- and negative-polarity sensitivity of fluorescence intensity. We explore two chalcones of opposite… read more here.
