The acidity constants of protonated naphthalene, anthracene, phenanthrene, chrysene, triphenylene and 1,2,5,6-dibenzanthracene in their lowest singlet and triplet excited states have been estimated by application of the Förster cycle to the electronic spectra of the neutral and protonated species ...
Study of the photodegradation and the “colorability” of non-azaheterocyclic spiropyrans by repeated flashes showed the influence of different effects involving the heteroatom, the substituent and the concentration. Substituents in 3′, 6′ and 8′ positions of the benzopyran part are very important...
