UV-driven photoredox processing of cyanocuprates can generate simple sugars necessary for prebiotic synthesis. We investigate the wavelength dependence of this process from 215 to 295 nm and generally observe faster rates at shorter wavelengths. The most efficient wavelengths are accessible to a range of potential prebiotic atmospheres, supporting the potential role of cyanocuprate photochemistry in prebiotic synthesis on the early Earth.
紫外线驱动的氰基铜酸盐光氧化还原过程能够产生益生元合成所需的单糖。我们研究了该过程在215至295纳米波长范围内的依赖性，并且通常观察到在较短波长下反应速率更快。一系列潜在的益生元大气都能接收到最有效的波长，这支持了氰基铜酸盐光化学在早期地球益生元合成中的潜在作用。
