  • Synthesis, structures and multifunctional sensory properties of poly[2,7-(9,9-dihexylfluorene)]-block-poly[2-(dimethylamino)ethyl methacrylate] rod-coil diblock copolymers
    作者:Sung-Tso Lin、Yi-Chih Tung、Wen-Chang Chen

    The synthesis, structures and multifunctional sensory properties of amphiphilic poly[2,7-(9,9-dihexylfluorene)]-block-poly[2-(dimethylamino)ethyl methacrylate] (PF-b-PDMAEMA) rod-coil diblock copolymers are reported. The new copolymers, with PDMAEMA coil lengths of 31, 45, 93 and 185 repeating units, were synthesized by atom transfer radical polymerization. The surface structures and photophysical properties of the synthesized polymers were studied through the variation of solvent composition (water–THF), temperature, and pH. The PF7-b-PDMAEMA45 structure changed from spheres to separate cylinders, bundles of cylinders and spiral-shaped micelles as the solvent composition changed from 0 to 90 wt% water in THF. However, the long-range order structure of spiral-shaped loops was not observed at a long coil length. The micellar aggregates of PF7-b-PDMAEMA45 in water showed a reversible surface structure transformation from cylinder-bundles to spheres on heating from 25 to 75 °C. The variation of the micelle size with temperature was judged to be similar from both atomic force microscopy (AFM) and dynamic light scattering (DLS) measurements. The intermolecular PF aggregations led to fluorescence quenching and a blue-shift in the absorption spectra of the block copolymer as the water content increased. The photoluminescence (PL) intensity of PF7-b-PDMAEMA45 in water was thermoreversible based on its lower critical solution temperature. The PL characteristics suggested the new copolymers behave as an on/off fluorescence indicator of temperature or pH, with a reversible “on–off” profile at an elevated temperature in water: the pH–fluorescence intensity profile switched from “off–on” to “on–off” as the temperature increased. The present study suggests that PF-b-PDMAEMA copolymers have potential applications as multifunctional sensory materials toward solvent, temperature, and pH.
    两亲性聚[2,7-(9,9-二己基芴)]-嵌段-聚[2-(二甲基氨基)乙基甲基丙烯酸酯](PF-b-PDMAEMA)棒状线圈二嵌段共聚物的合成、结构和多功能感官性能报道称。通过原子转移自由基聚合合成了 PDMAEMA 线圈长度为 31、45、93 和 185 个重复单元的新型共聚物。通过溶剂成分(水-THF)、温度和 pH 值的变化,研究了合成聚合物的表面结构和光物理性质。当溶剂组成从 0 wt% 水的 THF 溶液变为 90 wt% 水时,PF7-b-PDMAEMA45 结构从球形变为单独的圆柱体、圆柱束和螺旋形胶束。然而,在长线圈长度下没有观察到螺旋形环的长程有序结构。 PF7-b-PDMAEMA45 在水中的胶束聚集体在从 25 °C 加热至 75 °C 时表现出从圆柱束到球体的可逆表面结构转变。通过原子力显微镜(AFM)和动态光散射(DLS)测量,胶束尺寸随温度的变化被认为是相似的。随着水含量的增加,分子间 PF 聚集导致嵌段共聚物的荧光猝灭和吸收光谱蓝移。由于其较低的临界溶液温度,PF7-b-PDMAEMA45 在水中的光致发光 (PL) 强度是热可逆的。 PL 特性表明,新型共聚物可作为温度或 pH 值的开/关荧光指示剂,在水中高温下具有可逆的“开-关”曲线:pH-荧光强度曲线从“关-开”切换为“关-开”。随着温度升高而“开-关”。本研究表明,PF-b-PDMAEMA 共聚物作为溶剂、温度和 pH 值的多功能传感材料具有潜在的应用前景。

    One novel polystyrene-based copolymer (PS-PF) with p-conjugated unit (fluorneyl and phenyl rings) as pendant was designed and synthesized using radical polymerization method and initiated by AIBN (2,2-azobisisobutyronitrile) from the new functional monomer, which contained the conjugated unit and reactive double bond. Nuclear magnetic resonance, FT-IR and UV-visible spectra were used to characterize the structure of intermediate and copolymer. The PS-PF is easily dissolved in organic solvent such as THF and CH3Cl and to be formed thin film by spin coating. The ink-jet printing method was applied to form blue pattern. The strongest emission of the as prepared copolymer was at 416 nm with shoulder peak of 441 nm in the solution and 440 nm with shoulder peak in the film state.

  • Self-assembled structures in rod-coil block copolymers with hydrogen-bonded amphiphiles

    We report the synthesis and the self-assembled morphologies of a series of new rod-coil diblock copolymers, poly[2,7-(9,9-dihexylfluorene)]-b-poly(4-vinylpyridine) (PF-b-P4VP). The rod-coil diblock copolymers were synthesized via Suzuki coupling reaction and living anionic polymerization. Probing by transmission electron microscopy, small-angle X-ray scattering and atomic force microscopy, we found that the microphase separation varies from lamellar to cylindrical and then to spherical, depending on the length of P4VP blocks. The P4VP coil blocks were further hydrogen-bonded with 3-pentadecylphenol (PDP) to form rod-comb block copolymers. Similar to conventional coil-coil block copolymers-based supramolecules, the incorporation of PDP transforms the morphologies from lamellar to cylindrical or from cylindrical to spherical due to the increase of volume fraction of P4VP(PDP) comb blocks. The strategy described here can be used to tune the self-assembled structures of rod-coil block copolymers.
    我们报告了一系列新型棒卷二嵌段共聚物--聚[2,7-(9,9-二己基芴)]-b-聚(4-乙烯基吡啶)(PF-b-P4VP)的合成和自组装形态。这种棒卷二嵌段共聚物是通过铃木偶联反应和活阴离子聚合反应合成的。通过透射电子显微镜、小角 X 射线散射和原子力显微镜的探测,我们发现微相分离从片状到圆柱状再到球状的变化取决于 P4VP 嵌段的长度。P4VP 线圈嵌段进一步与 3-十五烷基酚(PDP)氢键结合,形成棒状-梳状嵌段共聚物。与传统的基于线圈嵌段共聚物的超分子类似,由于 P4VP(PDP)组合嵌段的体积分数增加,PDP 的加入会使其形态从片状变为圆柱状,或从圆柱状变为球状。本文所述的策略可用于调整棒卷嵌段共聚物的自组装结构。
