A thermally stable anthracene derivative for application in organic thin film transistors
A novel multifunctional anthracene derivative 2,6-bis(dibenzo[b,d]furan-3-yl)anthracene) (BDBFAnt), by coupling anthracene moiety with dibenzo[b,d]furan units attached to its peripheral position, has been designed and synthesized for application in OTFT devices. Introduction of dibenzo[b,d]furan units in OTFTs is the first example and is highly innovative due to their suitable carrier transport ability, excellent thermal stability, fine film-forming property, rigid planarity and outstanding fluorescence. The fabricated OTFTs demonstrate a decent hole mobility (3.0?cm2/V s) and favorable green solid fluorescence with excellent thermal stability (up to 220?°C), which expound on the great potential of our material in organic electronics.
