"molecular heterojunction rectifiers constructedy connecting porphyrinic 2D MOF nanosheets and oligophenylene thiols self-assembled monolayers within metal electrodes... rectification ratio >1.67 order magnitude... rectification variations come from adjustment of energy level alignment at OPT SAMs//2D MOF interface, leading to asymmetric charge transport with voltage polarities... universal/ flexible strategy for regulating electrical behavior without need for specific design and synthesis"
