A small‐angle neutron scattering investigation of metallo‐supramolecular micellar gels built from polystyrene‐ block ‐poly( tert ‐butylacrylate) PS‐ b ‐PtBA‐tpy (‐tpy: terpyridine) block copolymers and transition metal ions is presented. The influence of the copolymer concentration on the structure and spatial organization of the micelles, as well as the impact of the subsequent addition of metal ions (Fe(II), Ni(II), and Zn(II)) on these characteristics is extensively studied. The experimental scattering cross‐sections are fitted with an analytical formula based on the Percus–Yevick hard‐sphere model and on the Pedersen–Gerstenberg model for the structure and the form factor, respectively. The resulting structural information is correlated with previously performed light scattering and rheology experiments.
