The observation of
a reversible chemical transformation corresponding to an external
stimulus in the solid state is intriguing in the exploration of smart
materials, which can potentially be applied in molecular machines,
molecular switches, sensors, and data storage devices. The solid-state
photodimerization reaction of 1,3-bis[2-(4-pyridyl)ethenyl]benzene
(1,3-bpeb) in a one-dimensional coordination polymer {[Cd<sub>2</sub>(1,3-bpeb)<sub>2</sub>(4-FBA)<sub>4</sub>]·H<sub>2</sub>O}<sub><i>n</i></sub> (4-FBA = 4-fluorobenzoate) with 365
nm UV light afforded <i>syn</i>-tetrakis(4-pyridyl)-1,2,9,10-diethano[2.2]metacyclophane
(<i>syn</i>-tpmcp) in quantitative yield via a single-crystal-to-single-crystal
(SCSC) transformation. Upon irradiation with 254 nm UV light, an SCSC
conversion from <i>syn</i>-tpmcp to 1,3-bpeb was also achieved
in quantitative yield within the <i>syn</i>-tpmcp-supported
coordination polymer {[Cd<sub>2</sub>(<i>syn</i>-tpmcp)(4-FBA)<sub>4</sub>]·H<sub>2</sub>O}<i><sub>n</sub></i>. In particular,
accompanied by the reversible transformation between 1,3-bpeb and <i>syn</i>-tpmcp, the coordination chain exhibits photocontrollable
fluorescence-switching behavior, which makes this intelligent material
an appealing candidate for practical applications.
