This work is mainly focused on studies combining plasmonic nanostructures and π‐conjugated systems. It describes active molecular plasmonic devices in which π‐conjugated molecules and polymers, grafted on gold nanoparticles, are used to tune the plasmonic properties of metal nanostructures. It also explores two emerging research fields, i.e. plasmonic electrochemistry and plasmonic molecular electronics. In the former, electrochemical reactions are controlled and triggered by plasmons which yield various light‐induced electrochemical reactions at the nanoscale. In the latter, one combines molecular plasmonics and molecular electronics in plasmonic molecular devices. © 2018 Society of Chemical Industry

“…Moreover, the structure of composite devices should possess programmable features, such that the position and interval of components can be precisely manipulated. To date, various fabrication methods, including chemical or physical adsorption, cross‐linking by organic molecules and in situ growth processes, have been applied for Au nanoparticle/conducting polymer composite devices . However, it remains a formidable challenge to achieve the sequential arrangement of various components in an optimal manner during the fabrication of Au nanoparticle/conducting polymer composite structures …”

The negative differential resistance (NDR) effect observed in conducting polymer/Au nanoparticle composite devices is not yet fully clarified due to the random and disordered incorporation of Au nanoparticles into conducting polymers. It remains a formidable challenge to achieve the sequential arrangement of various components in an optimal manner during the fabrication of Au nanoparticle/conducting polymer composite devices. Here, a novel strategy for fabricating Au nanoparticle/conducting polymer composite devices based on self-assembled Au@PPy core-shell nanoparticle arrays is demonstrated. The interval between the two Au nanoparticles can be precisely programmed by modulating the thickness of the shell and the size of the core. Programmable NDR is achieved by regulating the spacer between two Au nanoparticles. In addition, the Au/conducting polymer composite device exhibits a reproducible memory effect with read-write-erase characteristics. The sequentially controllable assembly of Au@PPy core-shell nanoparticle arrays between two microelectrodes will simplify nanodevice fabrication and will provide a profound impact on the development of new approaches for Au/conducting polymer composite devices.
