promising synthetic tool to access a wider variety of π-conjugated polycyclic structures and thus to expand the potentialities of the “precursorapproach” for further improvements of molecular materials’ performances. This review gives an overview of synthetic strategies towards π-CPCs involving the
ultimate elimination of chalcogen fragments upon thermal activation, photoirradiation and electron exchange.
