Recent advances of crosslinkable organic semiconductors in achieving solution-processed and stable optoelectronic devices

Abstract

High-efficiency optoelectronic devices are attracting extensive attention nowadays. Besides efficiency, cost and long-term stability are also crucial parameters for judging the performance and application of optoelectronic devices. Multilayer solution processing technology has been proved to be an ideal and low-cost strategy. However, one of the key factors restricting this strategy is solvent erosion during subsequent solution-based device processing. Besides, the long-term stability is of vital significance for the lifetime of optoelectronic devices. Therefore, exploiting solvent-resistant and durable materials is urgently needed. Promisingly, crosslinkable organic semiconductors (COSs) can be crosslinked into an insoluble and stable network structure to achieve solvent resistance and improve long-term stability. In this review, the recent advances in COSs used in optoelectronic devices (organic photovoltaics (OPVs), perovskite solar cells (PerSCs), and organic light-emitting diodes (OLEDs)) are systematically summarized, in which the basic considerations and key challenges to realize solvent resistance and enhance long-term stability are presented first. Then, the significance, strategies, and disadvantages of COSs are introduced. Finally, typical applications of COSs in OPVs, OLEDs, and PerSCs and their prospects are discussed and highlighted. This review is expected to attract further considerable interest in COSs and promote further progress in optoelectronic devices.
