Functionalized UO2 Salenes: Neutral Receptors for Anions

The Supramolecular Attitude of Metal–Salophen and Metal–Salen Complexes

“…In compound 28 the contribution to phosphate (H 2 PO 4 -as tetrabutylammonium salt in DMSO) complexation given by the appended arm through H-bond interaction, is clearly reflected in the marked downfield shifts ∆δ = 0.7-0.9 ppm of the NH signals. Under the same conditions, complexation with chloride, sulphate, thiocyanate and perchlorate is not observed [43].…”

Di-palladium Complexes with Urea-containing Ligands as Anion Receptors

“…[16][17][18][19][20] Among the first examples of this approach are the metallocene-based receptors reported by Beer 14,21 and the uranyl complexes reported by Reindhout in which the host-anion interactions could be detected electrochemically. [22][23][24][25][26] Several groups have employed luminiscent ruthenium complexes with substituted bipyridines as chemical sensors for anions. [27][28][29][30][31][32][33][34][35] More recently, Gale and Loeb have reported a series of platinum complexes with substituted pyridine ligands as metalla-receptors for anions 20,36,37 while Anslyn has demonstrated that copper complexes of tridentate ligands (with a C 3v symmetry) can selectively bind phosphates with high associations constants.…”

Dmitry M. Rudkevich: A Tribute Seven Years after His Premature Passing

“…After this, he moved to Kiev, where he received his first Ph.D. degree in organic chemistry in 1989 from the Institute of Organic Chemistry of the National Academy of Sciences of Ukraine (Kiev) with Prof. Leonid N. Markovsky (now deceased). In 1992, he joined the research group of Prof. David Reinhoudt at the University of Twente in the Netherlands, where he worked on molecular recognition, [1][2][3] self-assembly, [4,5] and supramolecular chemistry of calix [4]arenes. [6][7][8][9] In 1995, he received his second Ph.D. in supramolecular chemistry with a Ph.D thesis entitled ''Calix [4]arenes in Molecular Recognition.''…”
