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

1,2-Di(9-anthryl) ethanes, accessible by thermolysis of lepidopterenes, undergo thermal and photochemical intramolecularDiels-Alderreactions to give 1,2-dihydroanthracenes whose aromatization leads to novel derivatives of triptycene.
10-dimethylanthracene (DMA) in chloroform occurs efficiently via the electron-transfer oxidation of DMA with the photoinducedelectron-transfer state of 9-mesityl-10-methylacridinium ion (Acr+-Mes), followed by deprotonation from the methyl group of DMA radicalcation and the radical coupling reaction between anthracenylmethyl radicals to produce dimethyllepidopterene.
