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

提出的研究重点是开发一种新的具有BPEA-TCNB CT配合物的有机光敏剂家族，其具有可改变的物质状态。为2022财年设定的中期目标包括：1)用制备的CT配合物和不同的三联体受体制作样品；2)进行ta - uc测量。那些预定的任务都很顺利地完成了。使用苝基三态受体的样品观察到阳性结果，但由于BPEA-TCNB CT配合物与三态受体之间的固体表面接触不良，即使在高激光功率下检测到的信号也出乎意料地弱。在样品准备方面需要进一步的修改，然而，由于我的雇佣合同到期，这个项目不幸不得不缩短。

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.
