Abstract
Although polymers have been
studied for well over a century, there are few examples of covalently linked
polymer crystals synthesized directly from solution. One-dimensional (1D)
covalent polymers that are packed into a framework structure can be viewed as a
1D covalent organic framework (COF), but making single crystal of this has been
elusive. Herein, by combining labile metal coordination and dynamic covalent
chemistry, we discovered a strategy to synthesize single-crystal metallo-COF
under solvothermal conditions. The single-crystal structure was rigorously
solved using single-crystal electron diffraction (SCED) technique. The
non-centrosymmetric metallo-COF allows second harmonic generation (SHG). Due to
the presence of syntactic pendant amine groups along the polymer chains, the metallopolymer
crystal can be further cross-linked into a crystalline woven network.
