Self-assembled monolayer FET based on a TTF derivative is described (FET = field-effect-transistor, TTF = tetrathiafulvalene). The molecule is anchored on an alumina dielectric layer through covalent bonding of a phosphonic acid linker. A p-type monolayer FET device is achieved and subsequent chemical doping of this monolayer with F4TCNQ dopants results in an ambipolar device. (F4TCNQ = 2,3,5,6-Tetrafluoro- 7,7,8,8-tetracyanoquinodimethane) Several strange behaviors including a gate voltage shift upon doping seem to be consistent with organic monolayer Mott FET. Finally, temperature dependence of the FET performance, which also fit the anticipated Mott FET behavior, is discussed.

This work identifies the dithiafulvenyl unit as an excellent electron donor for constructing D-π-A-type metal-free organic sensitizers of dye-sensitized solar cells (DSCs). Synthesized and tested are three sensitizers all with this donor and a cyanoacrylic acid acceptor but differing in the phenyl (DTF-C1), biphenyl (DTF-C2), and phenyl-thiopheneyl-phenyl π-bridges (DTF-C3). Devices based on these dyes exhibit a dramatically improved performance with the increasing π-bridge length, culminating with DTF-C3 in η = 8.29% under standard global AM 1.5 illumination.
