摘　　要：Self-assembled monolayers(SAMs)are the basic building blocks for bottom-up construction of organic electronics,which have garnered significant research interest in molecular electronics.However,structural defects and insufficient intermolecular coupling in SAMs result in low mobilities(10-5–10-2 cm2 V-1 s-1)in organic field-effect transistors(OFETs)[1],and attempts to improve the mobility of SAM-OFET achieved limited success.As a unique type of SAMs,monolayer molecular crystals(MMCs)(Fig.1a),featured by monolayer-molecular thickness and longrange ordered in-plane molecular packing,are expected to combine high-transparency and ultra-flexibility of SAMs with singlecrystal nature for high-performance OFETs.In the past decade,various approaches for preparing MMCs have been developed,and impressive optoelectronic performance has been realized in MMC-devices and MMC-based heterostructures,such as OFETs,OFET-based sensors,photodiodes,logic circuits,etc.
