(6,6)Carbon Nanobelt as a Synthetic Tool for Cycloiptycenes and Red Light Emitter
Share
(6,6)Carbon Nanobelt Bis(tetrahydrofuran) Adduct (I1078) is a new carbon material first synthesized in 2017 after more than 60 years of challenges.¹) It has a rigid belt structure of 12 fully fused benzene rings, is a partial structure of armchair-type carbon nanotube (CNT), and has properties similar to (6,6)CNT. The product shows red light emission with λem = 630 nm (λex = 500 nm in CH2Cl2). In synthesis, (6,6)carbon nanobelt reacts as a diene in the Diels–Alder reaction with arynes and alkynes such as diphenylacetylene (D0871), with the reaction taking place at the six central benzene rings. This method allows a variety of cycloiptycenes to be synthesized easily in one step.
