资源简介：
A photochemically
crushable and regenerative metal–organic
framework (DTEMOF) was developed
by complexation of photochromic ligand PyDTEopen and 5-nitroisophthalate (nip2–) with Cd2+ in DMF/MeOH. DTEMOF ([Cd(nip)(PyDTEopen)(H2O)(DMF)2]n) was obtained as colorless
crystals. Its crystal structure revealed that DTEMOF adopts a tubular structure with interlocked
coordination networks and can accommodate guest molecules in its one-dimensional
pores. When DTEMOF suspended
in DMF/MeOH was exposed to UV light, its crystalline network, though
thermally stable up to 260 °C, was readily crushed to afford
a homogeneous blue-colored solution, via ring-closing isomerization
of the constituent PyDTEopen ligand into PyDTEclosed. Upon successive exposure
of this solution to visible light, colorless MOF crystals identical
to those of DTEMOF were regenerated.
Light-responsive DTEMOF enabled
highly efficient on-demand guest release.
