Paper Abstract

Recent results are reported regarding the low temperature photochemistry and spectroscopy of several photoadducts of linear polyacenes blended into amorphous polymer hosts. The molecules studied are the anthracene-tetracene photoadduct, the 9-bromoanthracene-tetracene photoadduct, both isomers of ditetracene, and the D2h symmetric form of dipentacene (s-dipentacene). Low temperature fluorescence spectra and temperature cycling and matrix effects on photochemical hole burning spectra are presented. A discussion of the photochemical mechanism for some of the photoadducts which requires triplet-triplet absorption at low temperature is also presented.
