A hybrid metal phosphate-phosphite material grafted with electron deficient organic components showing interesting fluorescent and photosensitive properties

A new hybrid organic zinc phosphate-phosphite with a tris (4-pyridyl) triazine molecule embedded in the cavity of an extra-large 24-ring channel has been synthesized and characterized. A strong luminescence emission is observed, which is due to the close packed array of organic ligands. The covalent coupling of fluorescent and photochromic components builds a novel phosphate-based photoactive dyad system.
