Frontal ring-opening metathesis polymerization (FROMP) is a self-propagating, energy-efficient polymerization method used to fabricate polymeric materials. This dataset describes a photochemical approach for controlling the FROMP of dicyclopentadiene (DCPD). A photobase generator is used to inhibit polymerization under 365 nm light, while a photosensitizer combined with a co-initiator enables acceleration of the reaction under 470 nm light. Together, these components provide orthogonal, light-meditated control over front velocity.
