The introduction of a nitrogen atom in position 1 strongly modulates the electronic structures of the pyrene system and also notably stabilizes the HOMO and LUMO levels of pyrene. Hence, the conscious introduction of nitrogen atoms at a certain position of the pyrene scaffold facilitates the ...A new source of “CN” employing formamide and cyanuric chloride is introduced for the cyanation reactions.
