Ethereal solutions of the dianils I, when added under conditions of high dilution to a suspension of sodium sand in ether, give macrocyclic compounds II (n = 2–6) besides variable amounts of primary amines VI, secondary amines VIII and resinous products.
Construction of a Zn(II)–Eu(III) Nanoring with Temperature-Dependent Luminescence for the Qualitative and Quantitative Detection of Neopterin as an Inflammatory Marker
A nine-metal Zn(II)–Eu(III) nanoring 1 with a diameter of about 2.3 nm was constructed by the use of a long-chain Schiff base ligand. It shows a luminescence response to neopterin (Neo) through the enhancement of lanthanide emission with high selectivity and sensitivity, which can be used to quantitatively analyze the concentrations of Neo in fetal calf serum and urine. The luminescence sensing of 1
