  Highly Efficient Blue Electrophosphorescent Polymers with Fluorinated Poly(arylene ether phosphine oxide) as Backbone

  摘要：

  In view of the tolerance of F atoms in FIrpic to the nucleophilic aromatic substitution polymerization, an activated fluorinated poly(arylene ether phosphine oxide) backbone is used to construct novel blue electrophosphorescent polymers containing FIrpic as the blue emitter, because they can be synthesized under a milder temperature of 120 degrees C. Compared with the counterparts prepared at high temperature (165 degrees C), unexpected bathochromic shift is successfully avoided, and a state-of-art luminous efficiency as high as 19.4 cd A(-1) is achieved. The efficiency is comparable to the corresponding physical blend system, which indicates that the fluorinated poly(arylene ether phosphine oxide) has the potential to be used as the platform for the development of high-performance all-phosphorescent white polymer based on single polymer system.

  The construction of an all‐in‐one catalyst, in which the photosensitizer and the transition metal site are close to each other, is important for improving the efficiency of metallaphotoredox catalysis. However, the development of convenient synthetic strategies for the precise construction of an all‐in‐one catalyst remains a challenging task due to the requirement of precise installation of the catalytic sites. Herein, we have successfully established a facile bottom‐up strategy for the direct synthesis of Ni(II)‐incorporated covalent organic framework (COF), named LZU‐713@Ni, as a versatile all‐in‐one metallaphotoredox catalyst. LZU‐713@Ni showed excellent activity and recyclability in the photoredox/nickel‐catalyzed C−O, C−S, and C−P cross‐coupling reactions. Notably, this catalyst displayed a better catalytic activity than its homogeneous analogues, physically mixed dual catalyst system, and, especially, LZU‐713/Ni which was prepared through post‐synthetic modification. The improved catalytic efficiency of LZU‐713@Ni should be attributed to the implementation of bottom‐up strategy, which incorporated the fixed, ordered, and abundant catalytic sites into its framework. This work sheds new light on the exploration of concise and effective strategies for the construction of multifunctional COF‐based photocatalysts.

  摘要构建光敏剂和过渡金属位点相互靠近的一体化催化剂对于提高金属巯基氧化催化效率非常重要。然而，由于需要精确安装催化位点，因此开发便捷的合成策略以精确构建一体化催化剂仍是一项具有挑战性的任务。在此，我们成功地建立了一种简便的自下而上的策略，用于直接合成镍（II）共价有机框架（COF），并将其命名为 LZU-713@Ni，作为一种多功能一体化金属萘氧化物催化剂。LZU-713@Ni 在光氧化/镍催化的 C-O、C-S 和 C-P 交叉偶联反应中表现出优异的活性和可回收性。值得注意的是，与同质类似物、物理混合双催化剂体系，尤其是通过后合成修饰制备的 LZU-713/Ni 相比，该催化剂显示出更高的催化活性。LZU-713@Ni 催化效率的提高应归功于自下而上策略的实施，该策略将固定、有序和丰富的催化位点纳入其框架中。这项工作为探索构建基于 COF 的多功能光催化剂的简洁有效策略提供了新的思路。
