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.
