ERA NanoSci - Interfacing single molecules via nanoparticle networks
Theoretische Chemie: Elektronenstruktur, Dynamik, Simulation
Zusammenfassung der Projektergebnisse
In this ERANET-project, an European consortium tried to show that 2D gold nanoparticle arrays offer a versatile way to interface organic molecules, through an organized self-assembled structure of nanoparticles, to the nanoscale electrodes of a nanotrench device. Especially the ability to perform molecular exchange on 2D gold nanoparticle arrays enables to study built-in quantum mechanical effects and functional properties of tailoring-made molecules. Through this 2D gold nanoparticle arrays exchanged with Fe(BPP)2 molecules a resistance anomaly was exhibited. This resistance anomaly seems to be an intrinsic property of the spin crossover Fe(BPP)2 molecules. This is demonstrated via temperature dependent I-V measurements, R-T measurements, temperature dependent SERS analyses and SQUID measurements. The approach and innovation behind 2D Fe(BPP)2-gold nanoparticle arrays can lift up the nanoscience in self-assembled molecular-nanoparticle charge transport toward a valuable multifunctional nanotechnology.
