Synthesis and characterization of a main-chain-type conjugated copolymer containing rare earth with photocrosslinkable group

In this article, we report the design, synthesis, and characterization of a new main-chain-type rare earth-containing conjugated polymer with photocrosslinkable group. The polymer is crosslinked photochemically by the addition of a photoinitiator to yield an absolute insoluble network. The optical properties of the resulting conjugated polymer were characterized in solution, film state, and after photocrosslinking.
