Abstract

Poly(4-ethynylaniline) [poly(1)] coordinated to palladium nanoclusters (Pd NCs) were prepared. The coordination of Pd NCs was confirmed by X-ray photoelectron spectroscopy and scanning transmission electron microscopy. Pd NCs were coordinated with the benzene rings as well as amino groups of poly(1). Pd NCs were partly coordinated with the polymers, maintaining their original size to form the aggregates with sizes of several tens to hundreds nanometers. Pd NCs coordinated with poly(1) efficiently served as catalysts for the Mizoroki-Heck and Suzuki-Miyaura cross-coupling reactions.
