文摘
A highly luminescent two-dimensional metal鈥搊rganic framework (MOF) containing continuous 蟺-stack cylindrical arrays in a backbone has been designed and synthesized. Here, we demonstrate the 鈥渟upramolecular wire effect鈥?on a MOF surface for fast and reversible solid-state detection of both aliphatic and aromatic nitro explosives via a fluorescence quenching mechanism. A possible quenching mechanism by a supramolecular wire effect has been demonstrated by structural analysis of host鈥揼uest 蟺-stacked interactions and guest sorption studies.
