Abstract

Graphical abstract: A naphthalene-chromophore-based luminescent Zn(II)-organic framework exhibits 2-fold interpenetrated pcu framework, excellent stabilities and efficient TNP detection. Highlights: Naphthalene-based MOF (1 ) shows a 3-D 2-fold interpenetrated architecture. 1 has excellent thermal and solvent stabilities, and exhibits stronger emission. 1 shows efficient sensing ability toward TNP by luminescence quenching. Abstract: Naphthalene-chromophore-based ligands (BPN = 1, 4-Bis(4-pyridyl)naphthalene, H2 NDC = 1, 4-Naphthalenedicarboxylic acid) are exploited to fabricate a cluster-containing luminescent Zn(II)-organic framework [Zn2 (BPN)(NDC)2 ]n (1 ). Structurally, 1 is composed of binuclear [Zn2 (COO)4 ] paddlewheel clusters, BPN and NDC 2− bridges, and features a 6-connected (6-c) 2-fold interpenetrated pcu framework. 1 shows excellent thermal and solvent stabilities, and exhibits stronger emission than BPN and H2 NDC. Furthermore, luminescence performance tests demonstrate that 1 exhibits efficient sensing ability toward 2, 4, 6-trinitrophenol (TNP) by luminescence quenching response. Moreover, the quenching mechanism of 1 for TNP is discussed.
