Preparation of Field-Effect Transistors Comprising Compound 1b as Semiconducting Material

[0168] SiO.sub.2/Si substrates were thoroughly cleaned with piranha solution, ultrapure water, followed by isopropanol, and the substrates were functionalized with octadecyltrichlorosilane (OTS) from solution. A thin film of compound 1b was formed on the OTS-treated SiO.sub.2/Si substrate by spin coating a 5 mg/ml solution of compound 1b in CHCl.sub.3 at 4000 rpm for 30 sec, and annealed at 200° C. for 10 min on a hot-plate. On top of the organic thin film, Au layer was deposited through a shadow mask as source and drain electrodes to give top contact OFET devices. The channel width (W) was 3 mm and channel length (L) was 50 μm.

[0173] To record the transfer curve the drain-source voltage (V.sub.DS) was held to −80 V. The charge-carrier mobility (p) was extracted in the saturation regime from the slope of (I.sub.DS).sup.1/2 versus V.sub.GS using the equation p=2L/(W*C.sub.i)*(dl.sub.DS.sup.1/2/dV.sub.GS).sup.2, wherein L is the channel length, W is the channel width, C.sub.i is the capacitance per unit area of the dielectric layer, I.sub.DS is the drain-source current, and V.sub.GS is the gate-source voltage.

[0174] The threshold voltage (V.sub.th) was extracted from the intersection of the linear extrapolation of the I.sub.DS.sup.1/2 versus V.sub.GS plot with the V.sub.GS axis.
