Reacting 1,3-bis[2-(p-formylphenoxy)ethyloxy]-p-tert-butylcalix[4]arene 2 with 1,3-di(hydra- zinocarbonylmethoxy)-p-tert-butylcalix[4]arene 4 by 1+1 intermolecular condensation under diluted condi- tion, a novel biscalix[4]arene derivative 5 containing Schiff base and amide units was prepared in high yield.

By reacting 1,3-bis[2-(p-formylphenyloxy)ethyloxy]-p-tert-butylcalix[4]arene (1) with salicylide hydrazone or hydrazine hydrate in a "1+2"or a "2+2" condensation mode, a novel calix[4]arene derivative 2 or a biscalix[4]arene 3 bridged by benzalazine groups was conveniently obtained in a yield of 84% or 81%, respectively.
