In this thesis, poly(St-co-AMTPS) AIE NPs (named as SNPs) with various contents of AMTPS were synthesized through copolymerization of St and AMTPS in the water-borne miniemulsion systems。 The influence of the AMTPS content on the particle morphology and particle size, polymerization kinetics, luminescent properties of AIE NPs and copolymers were systematically studied。 According to the microscopic observation result, SNPs displayed a regular spherical morphology and had a narrow size distribution。 The kinetic results showed that all the polymerization rates of the systems with various AMTPS loadings were fast, and the St conversion could exceed 80% within 60min。 With the increase of the AMTPS content, the molecular weight of poly(St-co-AMTPS) decreased due to the chain transfer reaction of the propagated radicals to AMTPS。 SNPs could emit blue-green fluorescence under the irradiation of UV light, and the PL intensity of the AIE NPs could be precisely controlled by the loading of AMTPS。 It should be pointed out that the ФF of SNPs was relatively low, for example ФF of the SNPs with 20wt% of AMTPS was only 22。6%。 With the increase of the volume fraction of water in the tetrahydrofuran (THF)/water mixed solvent, the PL intensity of poly(St-co-AMTPS) gradually increased prior to 70%。 Further increase of the water fraction, the PL intensity of the copolymer was significantly enhanced, displaying a typical AIE behavior。 As the polymerization proceeded, more and more polymers were produced in the dispersed phase, leading to the increase of the viscosity of the dispersed phase。 In addition, with the accumulation of copolymers in the dispersed phase, the dispersed phase gradually transferred from a liquid state to a solid one。 Correspondingly, the PL intensity of the emulsion increased。

In conclusion, AIE polymer NPs can be conveniently prepared through copolymerization of a common monomer and an AIE functional monomer in green water-borne miniemulsions。 The proposed technique in this thesis holds high versatility and flexibility to prepare AIE NPs with a high PL intensity, high fluorescence quantum yield, and good biocompatibility。
