Electrochemically monitored fluorescence on plasmonic gratings: A first step toward smart displays with multiple inputs

Fluorenylporphyrins functionalized by electrochromic ruthenium units as redox-triggered fluorescence switches

The electrofluorochromic behaviour of two ruthenium-appended porphyrin dyads has been investigated. Differences in response according to the nature of the interposed aryl linker are rationalised with the aid of electrochemistry and TD-DFT calculations.

Tailored Surfaces/Assemblies for Molecular Plasmonics and Plasmonic Molecular Electronics

Molecular plasmonics uses and explores molecule-plasmon interactions on metal nanostructures for spectroscopic, nanophotonic, and nanoelectronic devices. This review focuses on tailored surfaces/assemblies for molecular plasmonics and describes active molecular plasmonic devices in which functional molecules and polymers change their structural, electrical, and/or optical properties in response to external stimuli and that can dynamically tune the plasmonic properties. We also explore an emerging research field combining molecular plasmonics and molecular electronics.

Tunable electrofluorochromic device from electrochemically controlled complementary fluorescent conjugated polymer films

The fluorescent behavior of the electrofluorochromic devices (Type I) of greenish-yellow emitting P1 and blue emitting P2 can be reversibly switched between the nonfluorescent (oxidized) state and the fluorescent (neutral) state with a superb on/off ratio of 23.8 and 21.9, respectively. Moreover, a tunable electrofluorochromic device (Type II) based on two P1 and P2 polymeric layers that are coated individually on two independent ITO electrodes shows switchable blue-white-(greenish-yellow) multifluorescence states.
