INOR 664 |
| In situ terminal alkyne coupling reactions were successfully used as a design element to synthesize microporous coordination polymers including 3,3'-(1,3-butadiyne-1,4-diyl)bis-pyridine copper, and 4,4'-(1,3-butadiyne-1,4-diyl)bis-benzoic copper. Longer/larger ligands 3,3'-(1,3-butadiyne-1,4-diyl)bis-pyridine and 4,4'-(1,3-butadiyne-1,4-diyl)bis-benzoate were formed in situ from 3-ethynylpyridine and 4-ethynyl benzoate. The single crystal x-ray structures showed that 3,3'-(1,3-butadiyne-1,4-diyl)bis-pyridine copper contains about 4Å 1D channels and 4,4'-(1,3-butadiyne-1,4-diyl)bis-benzoic copper contains about 12Å 1D channels. This new convergent method can overcome some limitations inherent in the traditional divergent approach, such as solubility and interpenetration. |
