Sensitizing low-energy light with organic charge-transfer complexes bearing modifiable states of matter: towards liquefied metal-free TTA-UC system

拟议的研究重点是开发一种新的有机光敏剂家族，其BPEA-TCNB CT络合物具有可修饰的物质状态。为2022财年设定的中期目标包括：1)用准备好的CT复合体和不同的三重态受体制作样品；2)进行TTA-UC测量。这些预定任务非常顺利地完成了。结果是阳性的样品，观察到使用基于茂金属的三重态受体，但检测到的信号出乎意料地弱，即使在高激光功率，因为较差的固体表面接触的BPEA-TCNB的CT络合物和三重态受体。将需要进一步修改样品准备，然而，不幸的是，由于我的雇佣合同到期，这个项目不得不缩短。

The proposed research focuses on developing a new family of organic photosensitizers with BPEA-TCNB CT complexes bearing modifiable states of matter. The interim goals set for FY2022 include 1) making samples with the prepared CT complexes and different triplet acceptors and 2) performing the TTA-UC measurements. Those scheduled tasks were completed very smoothly. Positive results were observed with the samples utilizing perylene-based triplet acceptors, but the detected signals were unexpectedly weak even with high laser power due to poor solid surfaces in contact between the BPEA-TCNB CT complexes and the triplet acceptors. Further modifications in sample preparations would be required, however, this project unfortunately has to cut short due to the expiration of my employment contract.
