摘　　要：A 1,10-phenanthroline based polymer named PPPhen(i.e.,polymer from pyrene 1,10-phenanthrolin)was prepared by the Friedel-Crafts reaction of 1,10-phenanthroline and pyrene cross-linked with dimethoxymethane.The related Pd catalyst Pd@PPPhen was prepared by supporting Pd nanoparticles(NPs)on the PPPhen material.PPPhen and Pd@PPPhen were characterized by means of scanning electron microscopy(SEM),transmission electron micro-scopy,N2 adsorption-desorption,Fourier-transform infrared and X-ray photoelectron spectroscopy analyses.Theresults showed that PPPhen polymer was highly porous and that the phenanthroline group can enliance the stability of the Pd nanoparticles.Pd@PPPhen also exliibited good catalytic activity in the aerobic oxidation of alcohols to aide-hydes and ketones,and Pd@PPPhen was recyclable with durable activity and retentive stmetures.
