Two Nickel(II) Coordination Polymers Based on Tri(p‐carboxyphenyl) phosphane Oxide with Highly Selectively and Sensitively Detection of Acetone

Abstract. Two nickel (II) coordination polymers, namely, {[Ni1/2(TPO)1/3(bib)1/2(H2O)]*H2O}n (1), and [Ni(HTPO)(bpy)(H2O)2]n (2), have been assembled from tripodal ligand of tripodal tri(p‐carboxyphenyl) phosphane oxide (H3TPO) and two N‐donors (bib = 1,4‐bis(imidazolyl)benzene, and bpy = 4,4'‐bipyridine). Their structures have been determined by single‐crystal X‐ray diffraction analysis and further characterized by elemental analysis, IR spectra, powder X‐ray diffraction (PXRD), and thermogravimetric analysis (TGA). Structural analysis reveals that complex 1 is an interestingly 3D (3,4)‐connected {103}2{106}3 net. While complex 2 is a 1D polymeric chain, which was further expanded into a 3D supramolecular structure through hydrogen bonds. Luminescent sensing measurements show two nickel CPs can selectively and sensitively detect for acetone from the normal solvents (DMF, DMA, DMSO, MeOH, EtOH, CH3CN, H2O, and N‐butanol).
