1.The behavior of 12 solid polycyclic aromatic hydrocarbons, subjected to the action of high pressure (up to 100 kbar) in conjunction with shearing stresses, was studied. Under these conditions, seven compounds exhibited the appearance (deepening) of a color and intense singlet EPR signals.2.A dark red substance (4–6% by weight), responsible to a substantial degree (50–70%) for the EPR signal, was isolated from “deformed” naphthalene; the IR spectrum of this substance showed a substantial difference from the spectrum of the initial naphthalene.3.The results of the investigation indicate the occurrence of chemical reactions of cleavage of individual covalent bonds, under the conditions studied, as well as the formation of conjugated polymers.4.The paramagnetic properties of deformed hydrocarbons evidently are due to the appearance of complexes with charge transfer among individual conjugated molecues. |
