Abstract
We present the first integration of a platinahelicene within a nanographene (NG), giving access to near-infrared circularly polarized phosphorescence with dissymmetry factors glum reaching 4 × 10−3. For comparison, a novel NG featuring a borahelicene displayed a blue-green circularly polarized fluorescence with glum = 6 × 10−4.
