Molecular recognition: Studies on the synthesis of some bis thiophene carboxamide derivatives as ditopic receptors for long chain dicarboxylic acids

Abstract

New molecular receptors 6, 7 and 8 with diphenyl ether/diphenyl sulphide as spacer having functional groups complementary to long chain dicarboxylic acids have been developed. Binding studies with different dicarboxylic acids showed high association constants with the receptor 6. © 2001 Elsevier Science Ltd. All rights reserved.
