The synthesis and characterization of a new, amino‐derivatized functional bis(salicylaldiminato)Ni II complex is reported. It is a useful and reactive precursor in the synthesis of polyimide thermosets. Thus, the first synthesis of a polyimide containing a nonlinear optical Ni II Schiff base complex in the main chain is achieved by thermally controlled film polymerization. Polymerization was monitored on silicon substrates by FT‐IR spectroscopy. The polymer film possesses characteristics analogous to those of the insoluble polymer obtained by polymerization in solution, as evidenced by FT‐IR spectroscopy and TGA analysis. The present approach might represent a general strategy for achieving thin films of insoluble, functional polymers. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
