A photoswitchable ligand based on azobenzene is self-assembled with palladium(II) ions to form a [Pd (E-L) ] cage. Irradiation with 470 nm light results in the near-quantitative switching to a monomeric species [Pd(Z-L) ] , which can be reversed by irradiation with 405 nm light, or heat. The photoswitching selectivity towards the metastable isomer is significantly improved upon self-assembly, and the thermal half-life is extended from 40 days to 850 days, a promising approach for tuning photoswitching properties.
一种基于偶氮苯的光开关配体与钯（II）离子自组装形成[Pd (E-L) ]笼。用470纳米光照射会导致几乎定量地转变为单体物种[Pd(Z-L) ]，该转变可通过用405纳米光照射或加热来逆转。自组装后，对亚稳异构体的光开关选择性显著提高，热半衰期从40天延长至850天，这是一种调节光开关性质的有前景的方法。
