Diindenoperylene (DIP), also known as diindeno[1,2,3-cd:1',2',3'-lm]perylene, is an organic semiconductor which receives attention because of its potential application in optoelectronics (solar cells, OLEDs) and electronics (RFID tags). DIP is a planar perylene derivative with two indeno-groups attached to opposite sides of the perylene core. Its chemical formula is C32H16, the full chemical name is diindeno[1,2,3-cd:1',2',3'-lm]perylene. Its chemical synthesis has been described.

DIP is a red dye and has been used as active material for optical recording.Because of its "perylene-type" optical emission in the visible spectrum, it has also been used in organic light emitting diodes.
