Abstract
The preparation of the first of a novel type of large thiophene-containing aza-crown ether is reported. The macrocycle is synthesised by linking a 3,4 -dialkoxythiophene moiety with two 3-hydroxythiophene units and ring closur e is effected by reaction with piperazine via the Mannich reaction.
