Construction of a Succinate-Bridged Cd(II)-Based Two-Dimensional Coordination Polymer for Efficient Optoelectronic Device Fabrication and Explosive Sensing Application

Abstract

A newly designed multifunctional two-dimensional coordination polymer (2D CP) {[Cd(suc)(4-nvp)2]·2H2O}n, (1), (H2suc = succinic acid and 4-nvp = 4-(1-naphthylvinyl)pyridine) has been synthesized and characterized by X-ray crystallography. The solid-state structure of the compound 1 reveals the formation of three-dimensional supramolecular architecture via C–H···π and π···π stacking interactions. Interestingly, the supramolecular assembly of compound 1 exhibits electrical conductivity in the semiconducting nature. A deep insight into the electrical study of compound 1 carried out by dielectric characterization reveals the enhancement of conductivity upon light soaking. Thus, the compound has potential applicability in the fabrication optoelectronic devices. On the other hand, compound 1 shows sensing activity toward explosive nitroaromatic compounds (epNACs), which threatens devastating terror attacks ultimately responsible for massive loss of life. Besides, the nitroaromatic compound (NAC) 2,4,6-trinitrophenol (TNP) can enter inside the mammalian digestive cycle, wherein it gets metabolized into a mutagenic species, picramic acid, which causes health hazards. Compound 1 can detect TNP with the most acceptable fluorescence method. Together with its optoelectronic device fabrication and explosive sensing application, the synthesized material can be used as a potential candidate for sustainability.
