A promising solution to the environmental instability of semiconducting organic materials is presented. Thin, highly ordered films (see Figure, a scanning probe microscopy image), fibers, and field-effect transistors (FETs), comprising chain-structures based on the so-called Magnus’ green salt, [Pt(NH3)4]-[PtCl4], were synthesized in aqueous media (see Cover). FETs were manufactured under ambient conditions from common organic solvents, and exposed—without significant loss of performance—to white light and air for periods of time in excess of 6 months, and to water of 90 °C for more than 12 h.
