The synthesis of macrocyclic chromogenic derivatives of pyrrole and imidazole is described. The complexing properties of these compounds with metal cations were investigated spectrophotometrically in acetonitrile. The synthesized crown ethers were also tested as ion carriers in ion-selective membran
High molecular-weight aromatic polyamides were obtained from 1,5-and 2,6-bis-(4'-carboxy-4-phenylenoxy-sulfony1)naphthalene by direct polycondensation reaction in N-methyl-2pyrrolidone with various aromatic diamines, using triphenyl phosphite and pyridine as condensing agents. The polymers were char
