Crystal structure of 7′-(4-chlorophenyl)-2′′-(4-methoxyphenyl)-7′,7a',7′′,8′′-tetrahydro-1′H,3′H,5′′H-dispiro[indoline-3,5′-pyrrolo[1,2-c]thiazole-6′,6′′-quinoline]-2,5′′-dione and an unknown solvent

Acta Crystallographica Section E: Crystallographic Communications, 2019
The asymmetric unit of the title compound, C34H28ClN3O3S, contains two independent molecules (A and B). They differ essentially in the orientation of the 4-methoxyphenyl ring with respect to the pyridine ring of the quinoline moiety; this dihedral angle ...

Spiropyran-Isoquinoline Dyad as a Dual Chemosensor for Co(II) and In(III) Detection

Molecules, 2017
Spiropyran derivatives have been studied as light-regulated chemosensors for a variety of metal cations and anions, but there is little research on chemosensors that simultaneously detect multiple metal cations.
