| 摘 要： | To allow anisotropies of optical properties in a magnetic field, nitroxide radical is introduced into the ortho-position of the phenylene ring in the side chain. A new azobenzene side-chain polymer (TEMPO-PAZ) containing TEMPOradical was synthesized. The polymer has a good solubility in organic solvents. The ESR spectrum of the polymer indicatedthree absorption lines characteristic of TEMPO radical. The optical phase conjugated responses (I_4) of the polymer filmswere investigated by degenerate four-wave mixing (DFWM). The experimental results showed that optical phase conjugatedresponse of the TEMPO-PAZ could be easily controlled by choosing the appropriate direction of magnetic field presumablydue to the nitroxide radical in the TEMPO-PAZ molecular structure. For the polymer investigated here, the nitroxide radicalwas introduced to increase optical phase conjugated response intensity in a magnetic field, aiming originally at searching fora new photo-active organic magnetic multifunctional materials.
