Towards new organometallic second-order nonlinear optical materials

摘要

We report on the synthesis of new organometallic donor-acceptor molecules for second-order nonlinear optics.They contair ferrocene as the donor group,cyano or tricyano-derivatized furan as the acceptor,and thiophene or 3,3'-bipyridine derivatives a:pi-bridge.These chromophores can be functionalized,in order to incorporate them later in polymers,covalently or not.
