Part of the Quantum Theory Chemical Reactions book series (QTCR, volume 2)


Polynuclear aromatic hydrocarbons (PAH) incorporated in rigid alkane matrices at 77K are photolysed under strong UV irradiation giving rise to monohydrogenated radicals and addition products of the matrix molecules to the PAH.Irradiating with medium UV light the reaction is biphotonic, the reactive state being an upper triplet. Taking anthracene incorporated in cyclohexane crystals added to liquid nitrogen, the photolytic products are oxidation derivatives of anthracene, cyclohexyl-9 anthracene and cyclohexyl-9, dihydro-9, 10-anthracene.

    Lesclaux, R. and Joussot-Dubien J. have shown that boric acid glass form a perfect matrix for photoionizing PAH since the solute molecules are trapped in non-hydrogen-bonded zone and that the hydrogen H, at some distant from the solute, can chemically and irreversibly trap photoejected electron.Google Scholar
