摘要: In the present work, two new chemical linkages (BPDA-PAM, BPDA-DG) are synthesized through reaction between 4,4'-biphthalic anhydride (BPDA) and acrylamide (AM), diethylene glycol (DG), respectively. Then novel series of multicomponent rare earth (Eu(3+), Tb(3+), Sm(3+)) polymeric hybrids have been assembled coordination bonding: one is from linkage BPDA-PAM to form BPDA-PAM-RE-phen(bipy) (2,2'-bipyridine (bipy) 1,10-penanthroline (phen)), other BPDA-DG compose BPDA-DG-RE-PVP PVP (PVP = poly vinylpyridine). These characterized especially photophysical properties (luminescence spectra, lifetimes quantum efficiencies) discussed in detail.
