Abstract: Two open-[60]fullerene–aniline conjugates were synthesized, where the π-conjugation is connected by an imino or amino group, and found to exhibit absorption bands tailing to 1100 and 1200 nm, respectively.

The reactions of cage‐opened C60 derivatives with aromatic diamines are known to cause an orifice‐enlargement in association with incorporating extended π‐systems. The present work focuses on 1,2‐, 2,3‐, and 1,8‐diaminonaphthalenes for the synthesis of a series of naphthalene‐fused fullerene derivatives. For the former two, orifice enlargement proceeded by cleaving two C=C bonds to afford an opening with a ring‐atom count of 20, in which the naphthalene moiety was fused by a pyrazine ring. For the reaction with 1,8‐diaminonaphthalene, only one C=C bond was cleaved to give a 17‐membered‐ring opening where the diaminonaphthalene moiety was fused by a pyrimidine ring.
