A photochemical "2 + 2 cycloaddition" reaction is proposed to drive the photopolymerization of pristine solid Csa. This mechanism proceeds via the triplet T, state and exhibits a temperature threshold near 250 K, close to the orientational ordering transition of solid Cm Below this threshold, the to
