Light-Controlled Reversible Modulation of Frontier Molecular Orbital Energy Levels in Trifluoromethylated Diarylethenes

Herder, Martin; Eisenreich, Fabian; Bonasera, Aurelio; Grafl, Anna; Grubert, Lutz; Pätzel, Michael; Schwarz, Jutta; Hecht, Stefan

Among bistable photochromic molecules, diarylethenes (DAEs) possess the distinct feature that upon photoisomerization they undergo a large modulation of their π-electronic system, accompanied by a marked shift of the ...
