Dynamics of singlet fission and electron injection in self-assembled acene monolayers on titanium dioxide

Autor: Dylan H. Arias, John E. Anthony, Natalie A. Pace, Justin C. Johnson, Steven T. Christensen, Devin B. Granger

Publikováno v: Chemical Science

Electron injection competes with singlet fission in disordered monolayers of tetracene and pentacene-based dyes on mesoporous TiO2 photoelectrodes.
We employ a combination of linear spectroscopy, electrochemistry, and transient absorption spectr
