ew ear Infrared Dyes and Fluorophores Based on Diketopyrrolopyrroles Dipl.-Chem. Georg M. Fischer, Dipl.-Chem. Andreas P. Ehlers, Prof. Dr. Andreas Zumbusch, Prof. Dr. Ewald Daltrozzo* Experimental Section General Solvents were purified according to standard procedures. Column chromatography was performed on Merck silica gel 0 (-00 Ñm, 70-0 mesh ASTM). MR spectra were recorded on a Jeol JM-GX-00 (00 Mz) spectrometer. The residual solvent peak was used as internal reference [CCl δ = 7.. C DCl δ =.98]. Multiplicity (singlet (s), broad (br), doublet (d), triplet (t), quartet (q) and multiplet (m)) and coupling constant(s) were reported whenever possible. MALDI-TF mass spectra were recorded on a Bruker Biflex III instrument in positive linear mode.,-dihydroxybenzoic acid (DB) was used as matrix. Elemental analyses were performed in the microanalytical lab of University of Konstanz with an C-analyser Vario EL from Elementar. Absorption and emission were recorded at ambient temperature ( ± C) using quartz -cm cuvettes ( ml). UV/Vis/IR absorption were recorded on a Varian spectrometer, Model Cary 0 and on a Perkin Elmer spectrometer, Model Lambda 9. Fluorescence was recorded at a self assembled IR fluorescence spectrometer with a nitrogen cooled germanium diode (orthcoast) as detector. For exitation a diode laser (80 nm, 0 mw, Laser 000 Model ACM0/7) or a e-e laser (.8 nm, mw, Spectra-Physics model 0-) were used. CZ (Φ F = 0,0 in C Cl at ambient temperature) was used as reference to determine the quantum yields. [7]

The solvent was refused from the filtrate and the blue : condensation product h was yielded by column chromatography (CCl /Me 0/) in %. The MgS was dissolved in water and the violet solid was filtered off. It was washed in water and digested with aceton in the ultrasonic bath. The solid was filtered of and washed with acetone.
