Abstract
The syntheses of various types of hexakis(4-functionalized-phenyl)benzenes I [R = CN, iodo, H2N, B(OH)2, n-C7H15CONH, n-C8H17NHCONH] and hexakis[4-(4'-functionalized-phenylethynyl)phenyl]benzenes I (R = 4-NCC6H4C?C, 4-pyridylethynyl, 4-HOC6H4C?C, etc.) by cobalt-catalyzed cyclotrimerization of diarylacetylenes and by Sonogashira coupling reaction of I (R = iodo) with arylacetylenes, resp., are described. X-ray crystallog. anal. showed that host I (R = iodo) or I (R = 4-HO2CC6H4C?C) forms a 2-D network by unique I···I or CH···O:C interactions, resp. [on SciFinder(R)]
