(b) Chemical formula and partial charge molecular model (yellow to red positive, cyan to blue negative) of two dendritic branches depicting the two modes of the molecular switch: spirolactam, ring-closed (A) amine external groups (C) (switch off) amide, ring-opened (B) aminium external groups (D) (switch on) Adapted with permission from [178]. (c) Schematic representation of TiO₂/CdS nanocomposite stabilized on a Fe₃O₄ core by PAMAM G0, G1 dendrons, and the photolytic mechanism for methyl orange.
