aLow-resolution TEM bright field image of the hybrid (1) after dilution. Small agglomerates due to the network formation are still visible (marked fields).bTEM micrograph (bright field image) of a diluted sample of hybrid (1) showing isolated Au nanocrystals of spherical shape and average diameter of about 2 nm. The insets show high-magnification images of an “ideal” cuboctahedral cluster with well-defined lattice fringes (A), and a multiple-twin particle (B) that exhibits different domains
