Photodimerization reaction of triple-stranded ladder coordination polymer via single-crystal-to-single-crystal transformation

Single-crystal-to-single-crystal (SCSC) structural transformation induced by light, heat and guest removal have received considerable interest in recent years, particularly, light-triggered SCSC transformations, which are displayed in several coordination polymers. Photochemical solid-state [2+2] cycloaddition reaction is the most studied reaction in solid-state chemistry and
