A macrocyclic compound contains linked together in a macrocycle at least one polyarylene unit containing 2 or more arylene rings and at least 2 other cyclic units, each of said polyarylene unit and said other units being linked to its neighbouring unit by a divalent single atom group or by an alkylene group. The compound can be made by ring-closure of a linear compound containing the arylene rings and other cyclic units and having 2 terminal halogens, preferably by the coupling reaction by zerovalent nickel. The compound can be polymerised by ring-opening in the presence of a catalytic quantity of a nucleophile.
