This catalyst is not only fast and easily tunable but also exhibits exceptional selectivity, outperforming traditional catalysts (such as thiourea, urea, and TBD) by 8 to 120 times. OPBU catalysts enable ROP of various monomers, achieving over 95% conversion in seconds to minutes, producing polymers with precise molecular weights and very low dispersity (\u0110 \u2248 1.01). Density functional theory (DFT) calculations reveal that the catalysts stabilize the oxyanion transition state via a hydrogen bond pocket similar to the &#8220;oxyanion hole&#8221; in enzymatic catalysis. These new insights provide a new class of organic catalysts with excellent performance and tunability, opening up new opportunities for controlled polymer synthesis.<\/p>\n<h4 style=\"text-align: justify;\"><strong>Q2. <\/strong><strong>\u6709\u5173\u672c\u6b21\u7814\u7a76\u7684\u65f6\u5019\u9047\u5230\u8fc7\u600e\u6837\u7684\u56f0\u96be\u5462\uff1f\u53c8\u662f\u600e\u6837\u514b\u670d\u7684\u5462<\/strong><\/h4>\n<p style=\"text-align: justify;\">\u5728\u8fd9\u9879\u7814\u7a76\u4e2d\uff0c\u6211\u4eec\u9047\u5230\u4e86\u4e24\u4e2a\u4e3b\u8981\u56f0\u96be\u3002\u9996\u5148\u662f\u5982\u4f55\u5bf9\u9009\u62e9\u6027\u8fdb\u884c\u5b9a\u91cf\u6d4b\u91cf\u3002\u4ee5\u5f80\u6587\u732e\u4e2d\u62a5\u544a\u7684\u65b0\u578bROP\u50ac\u5316\u5242\u901a\u5e38\u4ec5\u4f9d\u8d56GPC\u7ed3\u679c\uff0c\u7531\u4e8eGPC\u7684\u7cbe\u5ea6\u6709\u9650\uff0c\u96be\u4ee5\u76f4\u63a5\u6bd4\u8f83\u4e0d\u540c\u50ac\u5316\u5242\u7684\u9009\u62e9\u6027\u3002\u4e3a\u4e86\u89e3\u51b3\u8fd9\u4e2a\u95ee\u9898\uff0c\u6211\u4eec\u8bbe\u8ba1\u4e86\u4e00\u4e2a\u5b9e\u9a8c\uff0c\u4ee5\u66f4\u51c6\u786e\u5730\u4f30\u7b97\u94fe\u589e\u957f\u4e0e\u94fe\u8f6c\u79fb\u7684\u9009\u62e9\u6bd4\uff0c\u4ece\u800c\u5b9e\u73b0\u4e86\u5bf9\u8bb8\u591a\u4e4b\u524d\u50ac\u5316\u5242\u7684\u51c6\u786e\u6bd4\u8f83\u3002<\/p>\n<p style=\"text-align: justify;\">\u5176\u6b21\uff0c\u5173\u4e8eDFT\u8ba1\u7b97\uff0c\u6211\u4eec\u9762\u4e34\u4e86\u590d\u6742\u7684\u6311\u6218\u3002\u53cd\u5e94\u7269\u590d\u5408\u7269\u53ef\u4ee5\u5f62\u6210\u591a\u79cd\u4e0d\u540c\u7684\u6784\u8c61\uff0c\u4f7f\u5f97\u8ba1\u7b97\u53d8\u5f97\u975e\u5e38\u590d\u6742\u3002\u5c3d\u7ba1\u8fd9\u65b9\u9762\u6211\u4e0d\u662f\u4e13\u5bb6\uff0c\u4f46\u6211\u4eec\u7684\u5408\u4f5c\u4f19\u4f34Rachele Zunino\uff08\u5171\u540c\u4e00\u4f5c\uff09\u975e\u5e38\u51fa\u8272\u5730\u89e3\u51b3\u4e86\u8fd9\u4e2a\u95ee\u9898\uff0c\u6210\u529f\u5730\u5c55\u793a\u4e86\u5408\u7406\u7684\u53cd\u5e94\u673a\u5236\u3002<\/p>\n<p style=\"text-align: justify;\">We encountered two main difficulties in this research. First was developing a quantitative measurement of the selectivity parameter. Previously, new selective ROP catalysts reported in the literature usually relied solely on GPC results, which are not precise enough for good comparison between different catalysts. To address this, we designed kinetic experiments to provide a more accurate estimation of the selectivity ratio of chain growth versus chain transfer, allowing us to make fair comparisons among many previous catalysts.<\/p>\n<p style=\"text-align: justify;\">Second, regarding DFT calculations, we faced challenges due to the many different conformations that reactant complexes can access, making the computations very complex.
