Abstract
The phosphorylated calix[4]arenoid para- and meta-substituted cyclophane te tramers, which were synthesised in good yields starting from parent cyclic hydrocarbons, show a 'saddle-shaped' rigid conformation in solution, and th e methylenephosphonic acid dialkyl ester groups are in a strategic position far complexation with neutral guests.
