A new complex of indium(III)chloride with etioporphyrin-I was synthesized and characterized. As with naturally occurring extraligated etioporphyrins, the InCl-EtioP-I spectrum in solution has a very strong B-band and a more than an order of magnitude weaker Q-band, but this difference diminishes in solid films of InCl-EtioP-I obtained by thermal evaporation in vacuum. In a solid, molecules have a tight convex-convex arrangement in a 2D double layered structure with interplane distance of 3.066 Å. The conductivity of films can easily be activated by the action of temperature or light. In the cells with symmetrical lateral contacts the photocurrent exceeds the dark current by about three orders of magnitude, with the contribution of photons in the Q-band range being greater than expected from the experimental or calculated absorption spectrum. The Q-bands contribute significantly to the photovoltaic effect in the ITO/InCl-EtioP-I/Al sandwich cells. Such cells show an untypically strong signal in the photodiode regime, which yields the spectral detectivity of 10^12 Jones.
合成并表征了一种新的氯化铟（III）与粪卟啉-I 的配合物。与天然存在的配位粪卟啉一样，溶液中的 InCl-EtioP-I 光谱具有非常强的 B 带和一个数量级以上较弱的 Q 带，但这种差异在通过真空热蒸发获得的 InCl-EtioP-I 固体薄膜中减小。在固体中，分子在具有 3.066 Å 层间距离的 2D 双层结构中具有紧密的凸-凸排列。薄膜的电导率可以很容易地通过温度或光的作用来激活。在具有对称横向接触的电池中，光电流超过暗电流约三个数量级，其中 Q 带范围内的光子贡献大于实验或计算吸收光谱所预期的贡献。Q 带对 ITO/InCl-EtioP-I/Al 夹层电池中的光伏效应有显著贡献。此类电池在光电二极管区域显示出非常强的信号，其光谱探测率为 10^12 琼斯。
