Highly Efficient, Near‐Infrared Electrophosphorescence from a Pt–Metalloporphyrin Complex

Abstract

Red-shifting beyond red: The nonplanar porphyrin complex [Pt(tpbp)] (tpbp=tetraphenyltetrabenzoporphyrin) has been used as a phosphorescent dopant in highly efficient electrophosphorescent devices that emit in the near-infrared region (see normalized emission spectrum). The high efficiencies of these NIR devices make them amenable to many night-vision display and sensing applications.
