英文摘要	Hybrid nanoparticles of carboxyl-terminated generation 4.5 (G4.5) poly(amidoamine) dendrimers with platinum nanocrystals encapsulated inside them were prepared in water. The obtained nanoparticles were treated by size-selective precipitation to refine the size distribution. On a carbon-coated copper grid, the nanoparticles formed a monolayer film when observed by TEM. The sizes of the hybrid nanoparticles were evenly dispersed, with an average diameter of 4.0 nm. The Fourier transform power spectrum proved that the monolayer film had short-range order, and locally hexagonal packing was present. High-resolution transmission electron microscopy showed that the encapsulated Pt atoms were gradually rearranged as metal nanocrystals after a period of time.; Chemistry, Physical; SCI(E); EI; 0; LETTER; 4; 1176-1178; 108
