From isolated 1H-pyrazole cryptand anion receptors to hybrid inorganic–organic 1D helical polymeric anion receptors

摘要

We report on a novel 1-D helical coordination polymer formedby protonated polyamine 1H-pyrazole cryptands interconnectedby Cu2+ metal ions able to encapsulate anionic speciesbehaving as a multianion receptor. Switching from themonomeric to the polymeric receptor is activated by metal ionsand pH.
