On-surface polymerization is a promising technique to prepare organic functional nanomaterials, but it has remained difficult to carry out on insulating surfaces. Now, the photoinitiated radical polymerization of dimaleimide on KCl, initiated from a two-dimensional gas phase and guided by molecule–substrate interactions, has led to polymer fibres up to 1 μm long.
