Organic single-crystal light-emitting field-effect transistors

Thiophene-fused bowl-shaped polycyclic aromatics with a dibenzo[a,g]corannulene core for organic field-effect transistors

“…Many factors may influence the device performance based on single crystal mocro-wires or micro-ribbons such as packing mode, contacts between the micro-ribbons or wires and the dielectric. 30,[50][51][52] Nonetheless, the highest mobility based on corannulene derivatives was achieved by the extension of π-system and the adjustment of arrangement. In summary, we have developed a convenient way to extend the π-conjugation area of corannulene and to tune its arrangement.…”

Spiers Memorial Lecture : Organic electronics: an organic materials perspective

“…Though the community has been touting the advantages of OFET such as processing simplicity, light weight and flexibility, over the traditional electronics devices; a critical evaluation of the 20 ACTUAL costs involved in mass production, including switching from current synthetic methods to more environmentally friendly ones and to more efficient syntheses of the more complicated molecules, oligomers and polymers has yet to appear. 31 Torsi discussed a hybrid type of thin film transistor (TFT), the electrolytegated TFT (EG-TFT). In these devices, the electrolyte serves as a high dielectric 25 layer between the active layer and the gate.…”

Epitaxial growth of a methoxy-functionalized organic semiconductor on dielectric surfaces

“…[1][2][3][4] Depending on the application either the formation of continuous films or the growth of nanoaggregates (nanoclusters, nanofibers) is preferred. [5][6][7][8][9][10][11] Functionalization of the molecules can be used to improve or change the growth mode, preserving the optical properties. 12 In this work the growth of 1,4'''-Dimethoxy-4,1':4',1'':4'',1'''-quaterphenylene (MOP4) is investigated, i.e.…”
