A blue photoluminescent [Zn(L)(CN)2] (L = 2,2′-dipyridylamine) material with a supramolecular one-dimensional chain structure

Abstract

A novel blue luminescent [Zn(L)(CN)₂] complex (L = 2,2′-dipyridylamine) is synthesized and characterized by an X-ray diffraction study; the crystal packing in the Zn complex reveals that the molecules self-assemble by intermolecular hydrogen bonds [N–H···NC distance = 2.965(7) Å] and face-to-face π–π aromatic stacking interactions to form two-dimensional sheets.
