Electrically　bistable　devices　play　an　important　role　in　the　next　generation　of　information　materials.　Plasmonic　noble　metal　nanoparticles　(Au　and　Ag　NPs)　with　diameters　4,　which　can　be　attributed　to　its　higher　electron　tunneling　efficiency　because　of　the　better　dispersity　of　Au　NPs　in　the　MOF　matrix.　A　mechanism　regarding　the　electric-field-induced　charge-transfer　process　assisted　by　conformational　change　in　the　active　layer　was　proposed.　©　2019　American　Chemical　Society.
