N,
N-dimethylformamide and EtOH = ethanol), has been synthesized under mild conditions. X-ray crystallography reveals thatpolymer
1 consists of a 3D framework with an expanded diamondoid topology constructed from double 4-connected pentanuclear SBUslinked by rigid bpdc ligands. For an unusual pentanuclear framework, polymer
1 shows the favorable CH
3OH adsorption behavior andgood optoelectronic effect, which will facilitate the exploration of new types of multifunctional materials.
