    Bicyclic Guanidinium Tetraphenylborate: A Photobase Generator and A Photocatalyst for Living Anionic Ring-Opening Polymerization and Cross-Linking of Polymeric Materials Containing Ester and Hydroxy Groups
    摘要:
    1,5,7-Triazabicyclo[4,4,0]dec-5-ene (TBD) with pK(a) of 26.03 in acetonitrile can be effectively released by photolysis of TBD center dot HBPh4 salt, which represents a new family of short-wave UV photobase generators. This photobase generator enables the photoinduced living ring-opening polymerization of cyclic esters and the photoinduced cross-linking of various polymeric materials containing the hydroxyl-ester groups.

    摘要:
    控制环境亲核试剂对烷化剂的区域选择性是杂环化学中的一个基本问题。未取代的三唑特别具有挑战性,通常需要低效的逐步保护-去保护策略和预功能化方案。在此,我们报告了原型双基 1,2,4-三唑、1,2,3-三唑及其阴离子的烷基化,通过原位 1H/19F NMR、动力学模型、扩散有序 NMR 光谱、X 射线分析晶体学、高度相关的耦合簇计算 [CCSD(T)-F12、DF-LCCSD(T)-F12、DLPNO-CCSD(T)] 和 Marcus 理论。由此产生的机理见解允许设计一种有机催化方法,用于在未取代的三唑阴离子的直接 N-烷基化中进行环境控制。脒和胍受体显示出作为强协调相转移有机催化剂的作用,将三唑根阴离子穿梭到溶液中。在溶液中形成的紧密离子对保留了释放的三唑阴离子的反应性,但由于高度区域选择性的离子对,显示出完全反转(1,2,4-三唑)或显着增强(1,2,3-三唑)与母体阴离子相比。该方法允许一步直接获得

  • Introduction of Photolatent Bases for Locally Controlling Dynamic Exchange Reactions in Thermo‐Activated Vitrimers

    Vitrimers exhibit a covalently crosslinked network structure, as is characteristic of classic thermosetting polymers. However, they are capable of rearranging their network topology by thermo-activated associative exchange reactions when the topology freezing transition temperature (Tv) is exceeded. Despite the vast number of developed vitrimers, there is a serious lack of methods that enable a (spatially)
    Vitrimers 表现出共价交联的网络结构,这是典型的热固性聚合物的特征。然而,当超过拓扑冻结转变温度 (T v )时,它们能够通过热激活缔合交换反应重新排列其网络拓扑。尽管开发了大量的玻璃体,但严重缺乏能够(空间上)控制这些重排反应在 T v之上开始的方法。在此,我们强调了通过共价交联硫醇 - 环氧网络内光潜碱的紫外诱导裂解,高效酯交换催化剂 1,5,7-三氮杂双环 [4.4.0]dec-5-烯(TBD)的局部释放. 通过远高于网络 T 的应力松弛测量得到证明v,只有 TBD 的受控释放促进了在粘弹性流动方面的酯交换的立即发生。此外,空间分辨紫外线介导的玻璃体特性的光活化通过材料局部诱导的永久形状变化得到证实。
  • Thiol–epoxy/thiol–acrylate hybrid materials synthesized by photopolymerization

    Thiol–epoxy/thiol–acrylate hybrid networks with systematic variations (100/0, 75/25, 50/50, 25/75, 0/100, w/w) were prepared by free-radical photoinitiator (ITX) and photo-base generator (TBD·HBPh4) induced photopolymerization. The enhanced spectral sensitivity of TBD·HBPh4 at long wavelengths (320–500 nm) with aid of ITX was capable of in situ generation of a strong base (TBD) to achieve the relatively fast and essentially quantitative thiol–epoxy click reaction. The ITX/TBD·HBPh4 photoinitiating system, which generated both the free radicals and the strong base upon UV exposure, could induce thiol–epoxy/thiol–acrylate hybrid polymerizations. The kinetics investigated with real-time IR indicated that the thiol–acrylate reactions were faster and more efficient than the thiol–epoxy reactions (>95% conversion in a matter of seconds and minutes, respectively), and the thiol conversion increased with an increase in the epoxy concentration. The incorporation of the thiol–epoxy reaction offered several advantages: the polymerization shrinkage decreased with the increase in the thiol–epoxy content due to the low shrinkage factor for the thiol–epoxy system (every mole of epoxy group polymerized produces 6.3 mL of shrinkage). The glass transition temperature of the thiol–epoxy/thiol–acrylate hybrid networks progressively increased as a function of the thiol–epoxy content, also resulting in enhanced mechanical and physical properties. This work will be helpful to make optical and electronic devices with low shrinkage and stress, decreased residual monomers, and improved mechanical properties.
    通过自由基光引发剂(ITX)和光碱生成剂(TBD·HBPh4)诱导的光聚合,制备了具有系统变化(100/0,75/25,50/50,25/75,0/100,w/w)的硫醇-环氧/硫醇-丙烯酸混合网络。在较长波长(320-500 nm)下,TBD·HBPh4的光谱敏感性提高,配合ITX,能够原位生成强碱(TBD),从而实现相对快速且基本定量的硫醇-环氧点击反应。ITX/TBD·HBPh4光引发系统在UV照射下能够同时生成自由基和强碱,从而诱导硫醇-环氧/硫醇-丙烯酸的聚合。实时红外线研究的动力学表明,硫醇-丙烯酸反应比硫醇-环氧反应更快且效率更高(分别在几秒到几分钟内转换率超过95%),且随着环氧浓度的增加,硫醇的转化率也随之提高。引入硫醇-环氧反应带来了几个优点:由于硫醇-环氧体系的收缩因子较低(每摩尔聚合的环氧基团产生6.3 mL的收缩),聚合收缩随着硫醇-环氧含量的增加而减少。硫醇-环氧/硫醇-丙烯酸混合网络的玻璃转变温度随着硫醇-环氧含量的增加而逐渐升高,同时增强了机械和物理性能。这项工作将有助于制造低收缩和应力、减少残留单体、以及改善机械性能的光学和电子设备。
