The high resolution Sphol'skii fluorescence spectrum of the non-alternant polycyclic aromatic hydrocarbon cyclopenta[c,d]pyrene (CPP, 1) in an n-hexane matrix at cryogenic temperature is reported. Two distinct narrow spectral lines at 378.0 and 379.6 nm representing two sites were found, whereas in n-octane no Sphol'skii effect was observed. In accordance with reported data on the fluorescence of CPP (1) these lines have to be assigned to anomalous S-2-emission. (C) 1998 Elsevier Science B.V. All rights reserved.

Flash vacuum thermolysis (FVT) of 1-chloro-1-(pyren-1-yl)ethene at 1000 °C gives the combustion emittant cyclopenta[c,d]pyrene in good yields; the identification of 1-(pyren-1-yl)ethyne as an intermediate in the range 600–900 °C indicates that cyclopenta[c,d]pyrene is formed via an ethynyl–ethylidene carbene rearrangement.
