Synthesis, photophysical and nonlinear optical behavior of neodymium based trisphthalocyanine

• Dineodymium trisphthalocyanine was synthesized.
• The complex gave low fluorescence quantum yields.
• Nonlinear optical parameters were improved.
• Three reduction and two oxidation couples were obtained for the complex.

Tris-{1(4),8(11),15(18),22(25)-tetra(4-tertbutylphenoxy) phthalocyaninato} dineodymium (III) was synthesised and its nonlinear optical and fluorescence behavior was studied. Low fluorescence quantum yield (ФF = 0.03) was obtained with a fluorescence lifetime τF = 4.31 ns for this complex. Nonlinear optical parameters for the complex were determined using the Z-scan technique and the values of Im[χ(3)] and γ were of the order of 10−10 and 10−28 esu, respectively. Square wave voltammetry revealed three reduction and two oxidation couples for the complex.
