Oligodiacetylenes (ODAs) with alternating ene-yne conjugated structure are significant materials for optical and electronic properties. Due to the low solubility of ODAs in common solvents, the synthetic approaches arc liinited. Here we disclose a new synthetic approach of ODAs without a side alkyl chain using a porous coordination polymer (PCP) as a sacrificial template. 1,2-Bis(4-pyridyl)butadiyne, which works as a monomer, was embedded in the flexible framework of the PCP, and ODAs were synthesized via utilization of the anisotropic thermal expansion of the PCP crystal. The Oligomeric state of ODAs depends on the metal ion and coligand of the precursor.
