Two new molecular zinc phosphonates with bright luminescence for sensing UV radiation†
Abstract
Two new molecular zinc phosphonates, (HN(C2H5)3)4[Zn7(L)6]·2H2O (1) and [Zn9(L)6(H2N(CH2)2NH(CH2)2NH(CH2)2NH2)2]·18H2O (2) (H3L = 1-C10H7-CH2N(CH2COOH)(CH2PO3H2)), which consist of heptanuclear and nonanuclear zinc clusters, respectively, display bright luminescence for sensing UV radiation.
