Synthesis and Surface Characterization Studies of Polyether-Linked Symmetric Higher Sulfanyl-1,3,4-Oxadiazoles

The synthesis and the characterization of a series of novel symmetric double length alkyl-chained sulfanyl-1,3,4-oxadiazoles functionalized with a polyether head group are reported. In addition, surface characterization studies were conducted on the metal surface of these synthesized compounds. The metal surfaces were characterized by contact angle measurements via the sessile-drop method, and 3D images of the metal surface were obtained using an optical profilometer. The surface studies showed that the inhibitor molecule increases the hydrophobic character and decreases the wettability of the metal surface.

Molecular receptors for adenine and guanine employing metal coordination, hydrogen-bonding and π-stacking interactions

Thiacyclophane ligands 1 and 2, containing a meta-xylyldithiaether unit, an aromatic spacing unit and a polyether chain, were prepared in good yield in a three-step synthesis. The macrocyclic organopalladium complexes [Pd(L)-(MeCN)][BF4] (3: L =1; 4: L = 2) were prepared through palladation of the respective thiacyclophane ligand by reaction with [Pd(MeCN)4][BF4]2. These complexes act as metalloreceptors to aromatic amines such as p-aminopyridine (pap), m-aminopyridine (map) and the DNA nucleobases adenine and guanine. Binding occurs through simultaneous first- and second-sphere coordination. This involves three separate interactions: first-sphere σ donation from an aromatic N atom to the Pd centre. second-sphere hydrogen bonds between the NH2 group and polyether O atoms, and π stacking between the electron-poor aromatic rings of the substrate and the electron-rich aromatic spacing units of the receptor 1HNMR spectra exhibit chemical shift changes indicative of the H-bonding and π-stacking interactions in solution. X-ray structures for thiacyclophane 1, metalloreceptor [Pd(1)(MeCN)][BF4] (3), metalloreceptor/model substrate complexes [Pd(1)(pap)][BF4] (5) and [Pd(2)-(pap)][BF4] (7), and metalloreceptor/nucleobase complexes [Pd(1)(adenine)][BF4] (13), [Pd(2)(adenine)][BF4] (14) and [Pd(1)(guanine-BF3)][BF4] (15b) show details of these interactions in the solid state.
