An immobilized copper (II) complex on micro cellulose (Cell-DABCO-Cu) was synthesized and characterized by FT-IR, TGA, and SEM. The catalytic activity of Cell-DABCO-Cu was evaluated as a recoverable and green catalyst for the four-component synthesis of 2H-indazolo[1,2-b]phthalazine trione derivatives in solvent-free conditions. The notable advantages of this procedure include excellent yields, short experimental time, and easy preparation of the catalyst. The feature of this work is using of Cell-DABCO-Cu as a starting material to prepare single-phase CuO nanoparticles (CuO NPs) via a solid-state decomposition procedure. The CuO nanoparticles with an average size of 40 nm were obtained by the direct calcination of Cell-DABCO-Cu.
