Synthesis and optical properties of a crosslinkable polymer system containing TCF and TCP chromophores with excellent electro-optic activity and thermal stability

摘要

Crosslinkable polymer with side-chain system was investigated to increase the content of NLO chromophores andimprove the stability of oriented chromophores. In this work, a series of crosslinkable copolymers which beared different concentrations of chromophores with the tricyanofurane (TCF) acceptor and a kind of crosslinkable copolymers beared chromophores with dendritic tricyanopyrroline (TCP) acceptor were successfully synthesized and characterized. The crosslinked EO polymers which beared chromophores with the tricyanofurane (TCF) acceptor revealed the highest EO coefficient (rsub33/sub) of 47.0 pm/V at 1310 nm, which was similar with the r33 of uncrosslinked systems. Compared to the uncrosslinked EO polymer systems, the crosslinked ones exhibited significantly enhanced temporal stability.
