A novel light harvesting system that captures long-wavelength light of sunlight by the use of hole transfer was newly investigated. Ga phthalocyanine(GaIIITMAPc4+(D)) and Ru porphyrin(RuIIDMPyMP2+(A)) co-adsorbed reaction system on the synthetic nanosheet was examined as an artificial light harvesting system. By irradiating 660 nm light, where GaIIITMAPc4+(D) absorbs, to the system under a presence of PtCl62− as an electron acceptor, cation radical of RuIIDMPyMP2+(A) was produced despite that Ru porphyrin adsorbs only 413 and 533 nm light. The efficient hole transfer reaction from GaIIITMAPc4+(D)+, that is generated from its excited state, to RuIIDMPyMP2+(A) takes place on the nanosheet.

纳米片中的活性物种转移型人工集光系统–染料配合物:利用太阳光的较长波长区域

新研究了一种新型的光收集系统,该系统通过使用空穴传输来捕获长波长的阳光。将人工合成的纳米片上的Ga酞菁(Ga III TMAPc 4+(D))和Ru卟啉(Ru II DMPyMP 2+(A))共吸附反应体系进行了研究。在存在PtCl 6 2-作为电子受体的情况下,通过向Ga III TMAPc 4+(D)吸收660 nm的光照射系统,尽管Ru卟啉也产生了Ru II DMPyMP 2+(A)的阳离子基团。仅吸收413和533 nm的光。Ga的有效空穴转移反应从其激发态生成的III TMAPc 4+(D)+变成Ru II DMPyMP 2+(A)在纳米片上发生。
