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.
