      abstract     = {Harvesting triplet excitons of heavy atom-free purely
                      organic chromophores under aerated conditions is challenging
                      due to the quenching of long-lived triplet states by
                      molecular oxygen and vibrational dissipation. Herein, we
                      show a supramolecular approach of triplet harvesting via
                      mitigating quenching pathways of a triplet harvester.
                      Specifically, we used a host–guest system based on
                      2,3 : 6,7-naphthalene bis(dicarboximide)-derived
                      cyclophane (NBICy) and carbazole derivative (EtCz).
                      Complexation studies and single-crystal X-ray analysis
                      showed the formation of a rigid host–guest complex
                      (K≈10$^4$ M$^{−1}$ in CCl$_4$), resulting in
                      triplet-exciton stabilization under aerated conditions via
                      mitigating vibrational interference and oxygen quenching.
                      Photophysical studies elucidate the delayed fluorescence
                      emission from the charge-transfer state (1CT) with a quantum
                      yield (QY) of 6–8 \% under ambient conditions which
                      increased up to 36 \% in an inert atmosphere.},
