Description
Xu and co-authors merge, in 2026, bioinspired incubation with light-driven chemistry inside molecular capsules that mimic how enzymes cradle their starting materials. Their system tackles cutting carbon dioxide and the ring-closing cyclization of imines, reactions with high energy barriers normally demanding harsh settings, and runs them under mild settings with visible light instead.
At its best settings the capsule system produced about 1630 microliters of carbon monoxide within 30 minutes of irradiation at over 99 percent selectivity for the gas. For the ring closure, one substrate converted to its ring-closed product at 82 percent yield, a turnover number of 8200 per capsule in the reported runs. When activity faded, adding fresh reductant restored about 39 percent of the initial gas output, while fresh photocatalyst or capsule alone did not, naming what had shut the system down. The authors frame confinement inside capsules as a route past enzyme-like barriers.
