Functional Red-Emitting Organic Material for OPV and OLED Devices

Tetraphenyldibenzoperiflanthene (DBP) is an organic optoelectronic material that emits red light. In benzene solution, DBP shows high quantum yield fluorescence with maxima at 596 nm and 646 nm.¹) Its deep highest occupied molecular orbital (HOMO) energy level (-5.5 eV), efficient light absorption, and photochemical stability make it a donor material investigated for organic photovoltaic (OPV) devices.²,³) DBP is also an effective red dopant for organic light-emitting diodes (OLEDs), with emission colors close to the standard red CIE coordinates.⁴,⁵) In photon upconversion via triplet-triplet annihilation (TTA-UC), DBP has been doped as an emitter with rubrene as the acceptor, where improved quantum yields relative to the rubrene-only system have been observed.⁶,⁷)
