摘要：
In the present work, two new chemical linkages (BPDA-PAM, BPDA-DG) are synthesized through the reaction between 4,4'-biphthalic anhydride (BPDA) and acrylamide (AM), diethylene glycol (DG), respectively. Then two novel series of multicomponent rare earth (Eu3+, Tb3+, Sm3+) polymeric hybrids have been assembled through the coordination bonding: one is from the linkage BPDA-PAM to form the hybrids BPDA-PAM-RE-phen(bipy) (2,2'-bipyridine (bipy) and 1,10-penanthroline (phen)), the other is from the linkage BPDA-DG to compose the hybrids BPDA-DG-RE-PVP and PVP (PVP = poly vinylpyridine). These hybrids are characterized and especially the photophysical properties (luminescence spectra, lifetimes and quantum efficiencies) are discussed in detail.
