Two copper(I) coordination polymers, {[Cu2(4-bpo)2(MeCN)2(PPh3)2](BF4)2}n (1), {[Cu(4-bpo)(MeCN)(dppe)0.5]BF4}n (2) (PPh3 = triphenylphosphine, dppe = 1,2-bis(di-Ph phosphino)ethane, 4-bpo = 2,5-bis(4-pyridyl)-1,3,4-oxadiazole), were synthesized and characterized by IR, 1H NMR, 19F NMR, 11B NMR, elemental anal. and x-ray crystal structure anal. The structural anal. showed that complexes 1 and 2 consisted of diverse and interesting 2D supramol. structures formed by inter-chain interactions. For 1, π-stacking interactions result in the construction of 1D bilayer chain and 2D supramol. network. Compound 2 exhibits a 1D ladder-like chain and a 1D+1D→2D/3D supramol. structure formed by π-stacking interactions. Solid-state emission spectra of complexes 1 and 2 were studied, displaying the existence of ILCT/MLCT excited states. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Synthetic Route of C12H8N4O).
2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Synthetic Route of C12H8N4O
