A field‐induced chiral Yb III Single‐Molecule Magnet (SMM) displayed an unprecedented near‐infrared circularly polarized luminescence (NIR‐CPL) in the solid‐state. The bridging bis(1,10‐phenantro[5,6b])tetrathiafulvalene triad ( L ) allowed an efficient sensitization of the NIR 2 F 5/2 → 2 F 7/2 emission while the NIR‐CPL is associated to the f ‐ f transitions of the Yb III ion bearing chiral β‐diketonate derived‐camphorate ancillary ligands.
