Abstract:
Using polyhedral oligomeric silsesquioxane (POSS) modified by a thiol group as a protected ligand, atom‐precise multi‐heteorocluster‐based dendrimers Ag 12 @POSS 6 ( 1 a and 1 b ) were assembled. Through the reactive −SH groups, six POSS shell ligands stabilize the central 12‐core silver(I) cluster by diverse Ag−S interactions. When such Ag 12 @POSS 6 complex was stimulated by different solvents (acetone or tetrahydrofuran), the core Ag 12 silver(I) cluster underwent reversible structural transformation between flattened cubo‐octahedral (in 1 a ) and normal cubo‐octahedral (in 1 b ); concomitantly shell POSS clusters rearranged from pseudo‐octahedral to quasi‐octahedral. Furthermore, the film matrix modified by 1 a or 1 b showed different hydrophobicity.
