family of π-expandeddiketopyrrolopyrroles is described. A three-step strategy appears to be very general and starts with the preparation of diketopyrrolopyrroles followed by N-alkylation with bromoacetaldehyde diethyl acetal and electrophilic aromatic substitution. The final reaction regioselectively furnishes S-shaped, violet and blue functional dyes of previously unknown structure. New dyes possess

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
