Polyynes were prepared from pellets of a perylene derivative, 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA), and graphite by liquid-phase laser ablation, using solvents of methanol, ethanol, 1-propanol, 1-butanol, t butyl alcohol, n-hexane, and decalin The amounts of polyynes produced from PTCDA strongly depended on the polarity of the solvent, while those from graphite did not Polar functional groups of acid-anhydride side chains in PTCDA are believed to influence the amounts of C(2) radical
