The Effect of Auxiliary Nitrogenated Linkers on the Design of New Cadmium‐Based Coordination Polymers as Sensors for the Detection of Explosive Materials

Abstract Three new cadmium‐based coordination polymers, denoted [Cd(hfipbb)(4,4’‐bipy)] ( CdPF‐1 ), [Cd(hfipbb)(2,2’‐bipy)] ( CdPF‐2 ), and [Cd(hfipbb)(1,10‐phen)] ( CdPF‐3 ), have been hydrothermally synthesized by using the well‐known V‐shaped organic linker 4,4’‐(hexafluoroisopropylidene)bis(benzoic acid) (H 2 hfipbb), together with different nitrogenated auxiliary linkers. Considering the d 10 configuration of the transition metal selected, the luminescent properties for these CdPF‐ n materials were explored, finding that materials CdPF‐2 and CdPF‐3 act as excellent sensors in the detection of explosive nitro aromatic compounds. The photoluminescence properties of CdPF‐2 and CdPF‐3 revealed that significant and sensitive fluorescence quenching was observed toward NP (nitrophenol) for CdPF‐2 and PA (picric acid) for CdPF‐3 in MeOH suspensions.
