Translating controlled/living radical polymerization (CLRP) from batch to the high throughput production of polymer libraries presents several challenges in terms of both polymer synthesis and characterization. Although recently there have been significant advances in the field of low volume, high throughput CLRP, techniques able to simultaneously monitor multiple polymerizations in an “online” manner have not yet been developed. Here, we report our discovery that 5,10,15,20‐tetraphenyl‐21H,23H‐porphine zinc (ZnTPP) is a self‐reporting photocatalyst that can mediate PET‐RAFT polymerization as well as report on monomer conversion via changes in its fluorescence properties. This enables the use of a microplate reader to conduct high throughput “online” monitoring of PET‐RAFT polymerizations performed directly in 384‐well, low volume microtiter plates.

用于高通量RAFT聚合在线荧光监测的自报告光催化剂

在聚合物合成和表征方面，将受控/活性自由基聚合（CLRP）从批次转换为高产量生产的聚合物库提出了一些挑战。尽管最近在小体积，高通量CLRP领域取得了重大进展，但尚未开发出能够以“在线”方式同时监控多种聚合反应的技术。在这里，我们报告我们的发现，即5,10,15,20-四苯基-21 H，23 H卟啉锌（ZnTPP）是一种自报告型光催化剂，可介导PET-RAFT聚合反应，并通过其荧光性质的变化报告单体转化。这使得可以使用微孔板读取器直接在384孔小体积微量滴定板中进行PET-RAFT聚合反应的高通量“在线”监测。
