Abstract Molecular polaritons are hybrid light-matter states that emerge when a molecular transition strongly interacts with photons in a resonator. At optical frequencies, this interaction unlocks a way to explore and control new chemical phenomena

We study coupling of merocyanine to aluminum nanoantennas in weak and strong interaction regimes. Experiments reveal modification of the molecular dynamics induced by the plasmons as verified by quantum modelling of the hybrid system.

Evidence for Conduction Band-Mediated Two-Electron Reduction of a TiO2-Bound Catalyst Triggered by Visible Light Excitation of Co-Adsorbed Organic Dyes

Autor: Elin Sundin, Valeria Saavedra Becerril, Maria Abrahamsson

Publikováno v: The Journal of Physical Chemistry C. 122:25822-25828

Here, we report direct spectroscopic evidence of a visible light-induced two-electron-transfer reaction to a molecular model catalyst, facilitated by conduction band mediation. Using a simple, yet remarkably reproducible, co-sensitization approach, w

The electrolyte used in dye-sensitized solar cells (DSSCs) plays a key role in the process of current generation, and hence the analysis of charge-transfer mechanisms both in its bulk and at its interfaces with other materials is of fundamental impor

Extending charge separation lifetime and distance in patterned dye-sensitized SnO2–TiO2 μm-thin films

Autor: Elin Sundin, Mokhtar Mapar, Maria Abrahamsson, Valeria Saavedra Becerril

Publikováno v: Physical Chemistry Chemical Physics. 19:22684-22690

A simple method for the preparation of patterned dye-sensitized SnO2-TiO2 thin films, designed to prolong the lifetime of the interfacial charge separated state is presented. Using microfluidic technology, the thin films were sensitized with the orga

Ionic Liquid-Induced Local Charge Compensation: Effects on Back Electron-Transfer Rates in Dye-Sensitized TiO2 Thin Films

Autor: Valeria Saavedra Becerril, Maria Abrahamsson, Daniele Franchi

Publikováno v: The Journal of Physical Chemistry C. 120:20016-20023

The effect of ionic liquid electrolytes on back electron-transfer rates for dye-sensitized TiO2 thin films was investigated using microsecond–millisecond transient absorption. For D35/TiO2 and [Ru(dcb)3]2+/TiO2 in electrolytes based on 1-alkyl-3-me
