Stepwise ligand transformations through [2+2] photodimerization and hydrothermal in situ oxidation reactions

Abstract
The SCSC transformation of a 1D polymer [Cd(1,3-bdc)(4-spy)2]n produced a 2D polymer [Cd(1,3-bdc)(4-spy)(HT-ppcb)0.5]n through the [2+2] photodimerization reaction. Hydrothermal reactions of HT-ppcb with CdCl2, 1,3-H2bdc and H2O2 afforded another 2D polymer {[Cd(H2O)(1,3-bdc)(bpbpf)]·H2O}n in which HT-ppcb underwent in situ oxidation to form a unique furan-based ligand bpbpf.
