Abstract

We report on the fabrication of organic phototransistors based on the spiro-conjugated molecule 2,7-bis-(N,N[sup ′]-diphenylamino)-2[sup ′],7[sup ′]-bis(biphenyl-4-yl)-9,9[sup ′]-spirobifluorene. Intramolecular charge transfer leads to an increase in charge carrier density, providing the amplification effect. The sensitivity is better than 1 A/W for ultraviolet light at 370 nm, making the device interesting for sensor applications. © 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]
