How to create a chemical bond with light?

The formation of a chemical bond between two molecules often requires an activation process. Light is a stimulus that is particularly interesting

Polymers obtained by on-surface chemistry have emerged as a class of promising materials. Here, we propose a new strategy to obtain self-assembled 1D polymers by using photochemical [2+2] cyclo-addition. The mechanism of the photochemical reaction is highlighted in the video. The light acts as an external stimulus, allowing the reaction between adjacent molecules to give the corresponding 1D polymers. The results are fully described in an open-access publication: https://doi.org/10.3390/nano12081334

This work is supported by ANR.
