 Title    Darstellung und Charakterisierung von Tetraalkylammonium-lithium- phthaloeyaninen Preparation and Characterisation of Tetraalkylammonium-lithium-phthalocyanines  
 Abstract    The preparation of some tetraalkylammonium-lithium-phthalocyanines is described. In contrast to the known dilithium-phthalocyanine these quarternary "onium"-salts are, dependent on the size of the alkyl groups, soluble in non-polar, aprotic solvents. The electronic spectra are investigated as a film on a quartz disk at 10 K. Under these condi-tions a large number of narrow bands is observed instead of the normally diffuse ones. Solid state resonance Raman spectra were studied at 85 K by a method involving spinning KBr disks. It is shown that nearly all the lines are as a rule very sensitive to excitation conditions. The vibrational spectra are compared with the structural features of the compounds.
