TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: (I) comprises a gate dielectric layer, a gate electrode, a source electrode, the dry layer containing (II), and a drain electrode, where the dielectric layer, the gate electrode, the dry layer containing (II), source electrode, and the drain electrode are in any sequence as long as the gate electrode and thin organic semiconductor film both contact the dielectric layer, and the source electrode and the drain electrode both contact the dry layer of (II), where the dry layer of (II) is continuous. The article comprises: many electrically conducting gate electrodes disposed on the substrate, the gate dielectric layer disposed on the electrically conducting gate electrodes, the dry layer containing (II) disposed on the dielectric layer substantially overlapping the gate electrodes, and many sets of the source electrodes and drain electrodes disposed on the dry layer containing (II) such that each of the sets is in alignment with each of the gate electrodes. (II) is present in the dry layer at at least 98 and up to 100 wt.% based on total dry layer weight. The source, drain, and gate electrodes each independently comprise a material comprising doped silicon, metal, or a conducting polymer. The substrate is flexible. (I) comprises a flexible removable polymeric support that is adhered to a rigid substrate.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The dry layer consists essentially of (II); and an amine catalyst. (II) is thermally convertible to a semiconductive arylene diimide. The dry layer is a continuous layer; and a patterned layer. The dry layer further comprises an amine catalyst for the thermal conversion of the aromatic, non-polymeric amic acid salt to a corresponding arylene diimide. The aromatic, non-polymeric amic acid salt has a structure of formula (((A1)4N+) (O--C(=O)-Ar1(C(=O)-NH-A1)2-C(=O)-O-) ((A1)4N+)) (IIA) or (IIB).Ar1 = anthracene, naphthalene, or perylene nucleus and the four carbonyl groups are attached directly to peri carbon atoms; andA1-A3 (non-cation) = aryl, heteroaryl, non-aromatic alkyl, alkylaryl, fluoroalkyl, cycloalkyl, or heterocyclyl, and the four A1 groups in the cations represent the same or different H, aryl, heteroaryl, non-aromatic alkyl, alkylaryl, fluoroalkyl, cycloalkyl, or heterocyclyl.Provided that at least one of the A1 cation groups is H.
