Porphyrin face-coordinated AuNPs(π-conjugated AuNPs)were promising material for various applications including photo-electro conversion systems, while there has been no report about their photochemical behaviors. In this project, I synthesized a series of porphyrin π-conjugated AuNPs, and photochemical behaviours were investigated. It was discovered that intersurface interaction and excited state behaviour of the π-conjugated AuNPswere dramatically shifted depending on the molecular orientation. This result is an important insight for constructing solar cells. I presented a result of this project at the several conferences. The paper summarizing the results is under preparation.

卟啉面配位AuNPs（π共轭AuNPs）是一种有前景的材料，可用于包括光电转换系统在内的各种应用，但目前还没有关于其光化学行为的报道。在这个项目中，我合成了一系列卟啉π共轭AuNPs，研究发现，π 共轭 AuNP 的界面相互作用和激发态行为根据分子取向而发生显着变化。我在几次会议上介绍了该项目的结果，总结该结果的论文正在准备中。
