Abstract
A method of spectral analysis based on quasilinear luminescence spectra was used successfully for determining the degree of purity of coronene and pentacene. Despite its experimental simplicity, the method is very reliable and sensitive to various impurities exhibiting structured luminescence. The luminescence line spectrum of pentacene in the visible range, which can be useful in analysis, is also presented. Naphthalene was used as a solvent in addition to the usual normal paraffins.
