Chrysene‐Based Blue Emitters

Abstract Chrysene and its bisbenzannulated homologue, naphtho[2,3‐ c ]tetraphene, were synthesized through a PtCl 2 ‐catalyzed cyclization of alkynes, which also furnished corresponding biaryls subsequent to a Glaser coupling reaction of the starting alkynes. The optoelectronic properties of 5,5′‐bichrysenyl and 6,6′‐binaphtho[2,3‐ c ]tetraphene were compared to their chrysene‐based “monomers”. Oxidative cyclodehydrogenations of bichrysenyl and its higher homologue towards large nanographenes were also investigated.
