TIPS-triphenodioxazineversusTIPS-pentacene: Enhancedelectronmobility for n-typeorganicfield-effecttransistors
Résumé
A new soluble n-type material based on the 2,9-bis(triisopropylsilylethynyl)triphenodioxazine (TIPS-triphenodioxazine) has been designed as a quinonoid equivalent of TIPS-pentacene and synthesized using an innovative synthetic pathway. Both materials showed identical electronic affinities, intermolecular arrangements and thin film topographies. However, the TIPS-triphenodioxazine led to better performances than TIPS-pentacene in n-channel organicfield-effecttransistors (OFETs) evidencing the potentialities of this π-conjugated core in the field of organic electronics.
