| Abstract: | A series of novel acrylate monomers bearing stilbene segments with D-π -A structure, 4-methacrylate-4′-nitro stilbene (NS), 4-(6-methacrylate)hexyl-4′-nitro stilbene (HNS) and 4-(6-methacrylate)hexyl-2,3-dimethoxy-4′-nitro stilbene (DMHNS), were synthesized by the Witting reaction and polymerized by free radical polymerization. These stilbene-containing monomers and polymers were fully characterized, and their fluorescent properties in solution and solid state were also investigated. The emission band of monomers and corresponding polymers in solution also showed a remarkable effect with increasing polarity of the solvent. More importantly, the fluorescence emission could be adjusted from green to orange and even red regions by forming donor-π -acceptor (D-π -A) construction. |
