Abstract

A new metal-organic framework having formula {[Cd₃(H₂O)(L)₂][Cd(im)₃(H₂O)₂]·3 H₂O} (H₄L = 5-bis(4-carbonylbenzyl)aminoisophthalic acid and im = imidazole) (1) has been synthesized. X-ray investigation reveals that 1 is rare 4,4,8-connected (4⁶)(4⁵ · 6)(4¹¹ · 6¹⁵ · 8²) topology. The present work indicates that 1 could be a prospective candidate for developing novel luminescence sensors for the selective sensing of nitrobenzene which can be used as a precursor for explosives. Furthermore, the luminescent property of 1 in different solvents analytes as well as nitrobenzene have been investigated and the observed quenching in fluorescence have been corroborated by theoretical calculations.
