Synthesis and highly ordered thin films of optically active 2′-methoxy-1,1′-binaphthyl substituted phthalocyanines

The synthesis of metal-free and metal phthalocyanines modified with optically active binaphthyl 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 planes 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 layer.
