Nascut(a) in: 1939
Interese: heterocyclic chemistry, supramolecular chemistry,crystal engineering
Details:
I published over 85 scientific papers, in journals such as Angew.Chem.Int Ed., J.Am.Chem.Soc., Europ.Chem.J.,J.prakt.Chem. Talanta, J.Mass Spectrometry,in the field of heterocyclic chemistry, appliaction of catalysis in organic synthesis, supramolecular chemistry.My group reported for the first time the supramolecular association of icelike water hexamers into one dimensional tapes in an organic host. This work, published in Angew. Chem. Int Ed.2000.39.3094, has over 160 citations. I published a few books in the field of phase transfer catalysis, organic reactivity and one chapter in "Nanostructures, Novel Architecture" ed. M.Diudea, published by Nova Science Publishers, Inc. New-York.
