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 (Eu 3+ , Tb 3+ , Sm 3+ ) 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.
