We present near infra-red light-emitting diodes incorporating porphyrin hexamers as emitters in blends with F8BT. We have studied both linear and cyclic hexamers and obtain near infra-red emission from the linear hexamer with an external quantum efficiency (EQE) of 0.1±0.01 %. We also investigate the optical properties of such blends.
