Photodimerization of [(RuCp)(η6-dbqm)]+PF6â3(Cp =η5-cyclopentadienyl; dbqm = dibenzo-p-quinodimethane) in solution using visible light selectively afforded a stable organometallic adduct of the normally labile intramolecular photoisomer of [2.2](9,10)anthracenophane.
Multiple-Photon Chemistry of 9-(Phenoxymethyl)- and 9,10-Bis(phenoxymethyl)anthracenes in the Laser-Jet: Generation, Photochemistry, and Time-Resolved Laser-Flash Spectroscopy of Anthracenylmethyl Radicals and Pulse Radiolysis of 9-(Bromomethyl)anthracene
photons are required, the resulting arylmethyl radical 2a dimerizes in benzene, in methylene chloride it engages in photoinduced electron transfer, while in methanol it undergoes photoionization. With the help of time-resolved laser-flash photolysis of the monoether 1a it was confirmed that the homolysis of the C−O bond leads to the 9-anthracenylmethyl radical 2a. The authentic radi...

A series of linkedanthracenes capable of storing photon energy through endoergic valence photo-isomerization have been studied. Photophysical and photochemical characteristics of the systems have been completely characterized by measurement of fluorescence quantum yields and lifetimes, and efficiencies for forward and reverse isomerization. The release of energy stored in photoisomers has been measured
