| Popis: | A new derivative (PVK-Ox) of poly(vinyl carbazole) (PVK) was prepared by tethering oxetane pendants to the carbazole group through the decamethylene spacer. Photo-patternability of this new PVK-based polymer was investigated through photo-crosslinking reaction under UV light illumination (λ = 312 nm). We show that the chemical modifications as well as the cross-linking reaction do not degrade the optoelectronic performance of the starting polymer. The potential use of wide band gap cross-linkable polymers as electron-blocking layer is demonstrated. The results indicate that photolithography based on photo-crosslinking is a viable device fabrication tool for organic electronics. |
