New conjugated oligomers were synthesized by reacting diphenylacetylene at pressures of 0. 13 to 0. 76 GPa and at temperatures of 250 to 300°C for 1-10 h. The number-average molecular weight M<SUB>n</SUB> and the weight-average molecular weight M<SUB>w</SUB>, increased with pressure, but those values were independent of temperature and time (M<SUB>n</SUB>:320-490, M<SUB>w</SUB>:350-580). Elementary analysis, field desorption mass (FDMS) spectrometry, FTIR, and <SUP>13d</SUP>C NMR experiments revealed that the oligomers above and including pentamer were new compounds having cyclic structures.
