Combination of upper-rim-1,3-difunctionalized calixarenes 14, 16, and 18 with tribridged resorcinarenes 4 and 6 and A,C-di-bridged resorcinarenes 10 and 13 yields both 1/1 calix-resorcinarenes (22-24) and 2/1 calix-resorcinarenes (25, 26). 1/1 Calix-resorcinarene 22 mainly exists as one conformer (a), but at low temperatures (-60 deg C) very small amounts (arene fragments, 1,3-diaminocalixarene derivatives 31, 32, and 34 were synthesized carrying nitro, carboxylic ester, and cyano groups at the unsubstituted aromatic rings.With these calixarene derivatives, three new, functionalized 2/1 calix-resorcinarenes 35-37 have been synthesized.
