Clicking beyond suspensions: understanding thiol-ene chemistry on solid-supported MoS 2 .

Molecular functionalization of MoS 2 has attracted a lot of attention due to its potential to afford fine-tuned hybrid materials that benefit from the power of synthetic chemistry and molecular design. Here, we report on the on-surface reaction of maleimides on bulk and molecular beam epitaxy grown single-layer MoS 2 , both in ambient conditions as well as ultrahigh vacuum using scanning probe microscopy.
