【摘要】 光响应性高分子材料因其在信息存储、光学器件、药物运输、传感等领域的潜在应用而广泛的关注^[1]。我们将通过构筑聚合物无机多酸的杂化自组装体系,借助聚合物对紫外光的响应性,实现光诱导下多酸的功能调控。我们首先合成了具有光降解基团和氨基甲酸酯（-NHCOO-）结构的嵌段共聚物PEO₁₁₃-b-P(TEGMMA₆₆-co-C1NP₃₆),利用其光致断裂后生成的氨基正离子,与多酸阴离子Na₉DyW₁₀O₃₆通过静电相互作用形成了直径约10nm的球形胶束（Scheme 1）,多酸Na₉DyW₁₀O₃₆的荧光强度在光照后增强了近8倍,荧光颜色也从绿色变为白色^[2]。更多还原

【Abstract】 We synthesized a photo-responsive copolymer with the photocleavable groups as the pendant.The light-induced assembly was achieved through the electrostatic attraction between the protonated amine released from the polymer upon irradiation and the macroanionic Na₉DyW₁₀O₃₆.Sphere micelles with the diameter ¹0nm were formed under TEM observation.The emission intensity of Na₉DyW₁₀O₃₆ was obviously enhanced with ⁸ fold,accompanied by luminescent chromism from weak green to strong white.更多还原
