We report the detection of nitroaromatic vapors using a top-contact, bottom-gate organic field-effect transistor (OFET) by monitoring changes in the drain current. The active channel of the OFET contains a first generation dendrimer comprised of a spirobifluorene core, carbazole branching moieties, and fluorenyl surface groups. It is found that operating the device with pulsed gating reduces the bias...
A series of first generation dendrimers provide important insight into the performance of dye-sensitised solar cells (DSSCs). The dendrimers are comprised of a substituted [cis-di(thiocyanato)-bis(2,2′-bipyridyl)ruthenium(II) complex, first generation biphenyl-based dendrons, and either four, eight, or twelve 2-ethylhexyloxy surface groups. The dendrimers were bound to the titanium dioxide of the...
