calibration of fluorescence spectrometer at the time of original emission measurements led to wrong values of fluorescence quantum yields for diketopyrrolopyrroles described. We present here the correct values obtained during scrupulous measurements performed with a freshly calibrated apparatus. We also present slightly corrected absorption and emission spectra of π-expandeddiketopyrrolopyrroles. Page 2673

The invention relates to novel compounds of formula (III) that can be used as heterocyclic dyes of unique structure and properties. These compounds can be obtained in a three-step synthesis from simple substrates. The compounds according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the compounds according to the invention are used in organic field effect transistors, organic photovoltaics (solar cells) and photodiodes.
