o-Di-(pyrrole-2-carboxamides)-phenylene: pseudopolymorphs and anions recognition
摘要:
o-Di-(pyrrole-2-carboxamides)-phenylene (1) was synthesized and its two pseudopolymorphs were identified. A helical assembly was observed when it was incorporated with methanol molecules via hydrogen bonding, whereas a channel assembly was formed when it was associated with DMSO molecules. The H-1 NMR study revealed that 1 can recognize certain inorganic anions. (C) 2004 Published by Elsevier Ltd.
