Visible-light-mediated dehydrogenative cross-coupling between terminal alkynes and aldehydes by employing a supramolecular polymeric ensemble of PBI derivative

A supramolecular polymer of PBI derivative and ZnO NPs has been developed which exhibits remarkable efficiency in direct dehydro-genative cross-coupling between terminal alkynes and aldehydes for the synthesis of ynones under photocatalytic conditions.
