(Z)-2-(4-{[(E)-2-Hydroxybenzylidene]amino}phenyl)-3-[4-(1,4,7,10-tetraoxa-13-azacyclopentadecan-13-yl)phenyl]acrylonitrile

Abstract

The title compound, C32H35N3O5, is an important fluorescence probe. It is composed of a 1,4,7,10-tetraoxa-13λ2-azacyclopentadecane unit linked to a twisted (Z)-2-(4-{[(E)-2-hydroxybenzylidene]amino}phenyl)-3-phenylacrylonitrile chain. In the molecule, an O—H...N hydrogen bond forms an S(6) ring motif. There is also in intramolecular C—H...N hydrogen bond in the azacrown ether moiety, which also forms an S(6) ring motif. In the crystal, molecules are linked via pairs of C—H...O hydrogen bonds, forming inversion dimers.
