    The synthesis of metal-free and metal phthalocyanines modified with optically active binaphtyl is described. The structure is confirmed by 1H NMR, UV-Vis, CD, and MALDL-TOF MS. They can form stable monolayers at the air-water interface. In these layers, the phthalocyanines are stacked in edge-on arrangement. The monolayers can be transferred onto solid substrates and the resulting LB films are characterized by UV-Vis and CD spectra. In addition, AFM is employed to provide detailed information on the high resolution surface of the layer.
