| Popis: | Reactive vapor printing has emerged as an advantageous method to create conjugated polymer films with enviable electronic properties on prewoven fabrics. However, the conjugated polymers that have been vapor printed to date are exclusively hole transporters, since only monomers that can form radical cations participate in the oxidative polymerization reaction that underpins all existing vapor printing recipes. Here, we vapor print a conjugated polymer, PDTCPD, containing electron-withdrawing cyclopentadienone (CPD) moieties that depress its electronic energy levels and qualify it to serve as an electron acceptor when interfaced with known vapor-printed polymers. A custom-built hot wall reactor is shown to enable vapor-phase oxidative polymerization of a heavy CPD derivative to create PDTCPD films. Vapor printing is particularly useful for creating films of CPD-containing polymers because these intractable materials cannot be processed using solution-based methods. Vapor printing yields uniform and conformal PDTCPD films on topographically complex fabrics with minimal evident erosion upon solvent rinsing. This work provides a route to construct wearable optoelectronic devices that include monolithically-integrated active layers. |
