DBP, promising organic small-molecule semiconductor

Electron donor and acceptor for highly efficient photovoltaic and OLED applications


5,10,15,20-Tetraphenylbisbenz[5,6]indeno[1,2,3-cd:1′,2′,3′-lm]perylene (DBP), also known as tetraphenyldibenzoperiflanthene, is a promising organic small-molecule semiconductor. It can be used as either an electron donor or acceptor for highly efficient photovoltaic and OLED applications.

With perylene as an electron-rich core and extended conjugations, DBP can also be used in photovoltaic light-emitting diodes (PVOLEDs) devices as an electron-donating layer (EDL) material.
