UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe synthesis and novel conformational properties of doubly and triply intrabridged calixarenes 1 and 2 are presented. Compound 1 is shown by VT-NMR and 2D EXSY NMR to exist in CDCl3 solution as a mixture of 1,2-alternate and cone conformers, while 2 adopts predominantly an asymmetrical conformation at temperatures below 235 K. Compound 1 in the solid state, determined by X-ray crystallography, exists in a very distorted cone-shaped conformation.
