Tris-{1(4),8(11),15(18),22(25)-tetra(4-tertbutylphenoxy) phthalocyaninato} dineodymium (III) gave low fluorescence quantum yield but improved nonlinear optical parameters. [Display omitted] •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=4.31ns 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 10−28esu, respectively. Square wave voltammetry revealed three reduction and two oxidation couples for the complex.
