Abstract

Two novel calix[4]arene-based tetrapyrazolyl cavitands with different cavity size were synthesized by multistep reactions. In the solid state, one of the cavitands forms an infinite chain by ­intermolecular hydrogen bonding. The other cavitand undergoes coordination self-assembly with dimetal corners to form a supramolecular cage.
