A novel octupolar chromophore with 1,3,5-triazine as core, 2,7-divinylene-9,9-dimethylfluorene as extended π-conjugated bridge, triarylamine as the electron-donating end-groups was successfully synthesized and characterized. Their linear photophysical and two-photon absorption (TPA) properties were investigated by UV absorption, excited fluorescence (SPEF) spectra and nonlinear transmission method, respectively. The absorption cut-off of the chromophore is below 520 nm and it has stronger fluorescence emission in a nonpolar solvent. In addition, the chromophore exhibits larger TPA cross-section (226.0 GM) in the femtosecond regime at 800 nm.

The invention provides a novel preparation method of sulfonium salt derivatives with stilbene as a conjugated system. The method comprises steps as follows: firstly, benzyl halides (Hal denotes halogen atom) substituted with different groups react with organic phosphate, a product reacts with benzaldehyde substituted with different sulfydryl under the alkaline condition, a high-yield disubstituted stilbene intermediate shown in (I)-a is prepared, and finally, the intermediate shown in (I)-a produces final sulfonium salt under the action of silver salt and alkyl halide or silver salt and alkyl acid ester; when different negative ions are required to be replaced, a salt exchange method is adopted to realize replacement. The provided scheme has the benefits, as examples but not confined, as follows: no noble metal catalyst is required, the raw materials are easy to obtain, and the cost is low; the reaction is performed at the room temperature, operation is simple and purification is convenient; favorable conditions are provided for large-scale industrial production of the sulfonium salt derivatives with stilbene as the conjugated system.
