Chem., 2014, 5, 6216 PDF 【文章简介】：本文主要研究了在多壁碳纳米管存在的条件下对三种单糖修饰的单取代聚炔进行了聚合（即原位聚合），这种原位聚合实现了聚炔与多壁碳纳米管的杂化复合，而且多壁碳纳米管的质量分数超过了2%，经过一系列的数据的表征发现，聚合物主链的类似苯乙烯的结构和碳纳米管之间的π-π相互作用对碳纳米管的分散性起主要作用，利用原位聚合的方法，制备了壳聚糖和杂化材料的复合体，经过力学分析发现，复合体的弯曲强度和模量比原始的壳聚糖更高。( This paper mainly realized the polymerization of monosaccharide-functionalized monomers in the presence of MWCNTs (in situ polymerization). This method leads to the hybrids of monosaccharide-functionalized PPAs/MWCNTs, and the content of MWCNTs is over 2% by weight. The characterization data indicates that the π– π interaction between the styrene-like moieties in the polymer backbone and the MWCNTs plays crucial role in the dispersing capacity. Based on the in situ precipitation method, CS rods containing monosaccharidefunctionalized PPAs/MWCNTs hybrids were fabricated. The bending strength and modulus of the hybridreinforced CS rods showed substantial improvement in comparison with the CS rods made from pristine and hydroxyapatite-reinforced CS)

Catalyst-Free Thiol−Yne Click Polymerization: A Powerful and Facile Methodology for Preparation of Functional Poly(vinylene sulfide)s. Bicheng Yao, Ju Mei, Jie Li, Jian Wang, Haiqiang Wu, Jing Zhi Sun, Anjun Qin* and Ben Zhong Tang* Macromolecules, 2014, 47, 1325-1333. PDF 【文章简介】：传统的硫醇−炔点击反应或点击聚合往往都需要光、热引发剂，有机酸、碱促进剂，或者有机金属配合物的催化作用才能顺利进行。本文中，我们报道了一种无需加入任何催化剂的硫醇−炔点击聚合方法。如TOC所示，将等摩尔量的芳香二炔单体和二硫醇单体溶解在四氢呋喃中，室温下，仅仅反应两小时就可以得到高分子量的聚乙烯基硫化物PVS，产率很高，聚合物的溶解性与空间选择性也较好。此外，我们还通过该聚合方法制备了具有高折光指数和具备聚集诱导发光性能的PVS，它们在光学材料和化学传感等领域有着潜在的应用。(A green and energy saving polymerization methodology was developed from thiol−yne click chemistry. Unlike orthodox photo- or thermo-initiated ones, this thiol−yne polymerization could be facilely carried out under very mild conditions without any external stimulus. Simply mixing the aromatic diynes and dithiols with equivalent molar ratio in THF at 30 °C will readily produce soluble and regioregular poly(vinylene sulfide)s with high molecular weights (Mw up to 85 200) in excellent yields (up to 97%) after as short as 2 h. This catalyst-free thiol−yne click polymerization has remarkably simplified the reaction conditions and will facilitate the preparation of functional materials applied in diverse areas.)

Kwok, Engui Zhao, Jing Zhi Sun, Anjun Qin* and Ben Zhong Tang* Scientific Reports, 2014, 4, 5107, 1-5.PDF 【文章简介】普通的点击聚合反应由一价铜复合物催化进行，但是此类催化剂非常难从聚合产物中分离出来，而且，铜对聚合物的光电性能有害，同时，铜还有生物毒性。因此，我们开发了一种新型的负载型点击聚合催化剂，该负载型催化剂可以在温和的条件下催化叠氮和炔烃单体的点击聚合反应，得到低铜残留量的聚三唑产物。此外，此负载型催化剂还可以重复利用，经济实用。 ( Typical azide-alkyne click polymerization is catalyzed by Cu(I) complexes, which are difficult to completely removed after reaction and will detriment the optoelectronic properties of the polymers, or cause cytotoxicity in their biomedical application. Herein, we describe an efficient supported Cu(I) catalyzed azide-alkyne click polymerization under mild condition, and polytriazoles with low copper content were produced. Furthermore, this catalyst is reusable for 4 cycles.)

Chem., 2014, 5, 2309-2319 PDF 【文章简介】：我们合成了两种末端含有烯键的双取代乙炔单体并使用WCl6–Ph4Sn催化剂聚合得到聚乙炔。该产物可作为前体聚合物，进一步与硫醇发生硫醇-烯点击反应，从而得到新型双取代聚乙炔。不仅如此，活化的末端双键还可发生Michael加成反应。这些结果表明硫醇-烯反应和Michael加成反应是使用聚合后修饰策略合成新型功能化双取代聚乙炔的可行方法。(Two disubstituted acetylenes bearing vinyl group at one end were synthesized and polymerized by WCl6–Ph4Sn catalyst. The expected poly(disubstituted acetylenes) were used as precursors to be subsequently modified with a mercapto compound through the thiol–ene click reaction to produce the novel PDSAs in good yield. Moreover, the activated end-ene group allowed the post-polymerization modification by Michael addition reaction. These results indicated that the thiol–ene click reaction and Michael addition reaction are accessible routes for post-polymerization modification to generate novel functional PDSAs.) |
