Abstract :
We synthesized and studied sandwich complexes where a lanthanide is coordinated with two phthalocyanine rings. Study of nonlinear optical properties was tested with using the XeCl (308 nm, 10 ns) and second harmonic of Nd:YAG (532 nm, 15 ns) laser. In this experiment were estimated the coefficient of limitation, quantum phototransformation yields and the quantum yield in the triplet state from spectral-luminescent characteristics. Much attention is given to studying of ionic and neutral forms of sandwich complexes in the basic and excited states.
