摘要

The results of 13C-{19F} rotational-echo double-resonance (REDOR) NMR experiments performed on fifth-generation poly(benzyl ether) dendrimers synthesized by convergent methods are presented. Fluorine was used to label the ring-C-1 of the first generation and 13C to label the methylene carbons of either the third or fifth generations. The generational layer is the monomeric repeat-unit layer counted outward from the focal point, the first methylene carbons are considered part of the first generation, so that the dendrimer terminates with the fifth-generation methylene carbons coupled to the chain-end phenyl rings.
