Abstract
Solvothermal reaction of Zn(NO 3 ) 2 with 2,9-bis-(2-pyridine-3-yl-vinyl)-[1,10]phenanthroline (3-bpep) and furan-2,5-dicarboxylic acid (2,5-H 2 FDC) afforded a one-dimensional (1D) coordination polymer {[Zn 2 (3-bpep) 2 (2,5-FDC) 2 ]·1.5H 2 O} n (1), which undergoes regioselective photocycloaddition to yield another 1D coordination polymer {[Zn 2 (3-bpep)(trans,rctt-3-bpbpycb) 0.5 (2,5-FDC) 2 ]·H 2 O} n (2) in a single-crystal-to-single-crystal manner under UV light irradiation. The reverse process from 2 to 1 can be achieved by heating 2 at 240 °C. Such a photocycloaddition/thermocycloreversion cycle results in an interesting reversible dielectric switching.
