Abstract
Polyynes have been radiolyzed with a 60Co γ‐source in the absence of air at various radiation doses from 1 to 20 kGy. The disappearance of polyynes C8H2, C10H2, C12H2, has been followed by liquid chromatographic analysis (HPLC) using a diode array and a fluorescence detector. The polyynes radiolysis has been followed as function of the irradiation time. The HPLC analysis has revealed that initially C8H2 is transformed into a derivative having higher molecular weight which is then demolished into other products. The final products analyzed by FT‐IR spectroscopy appear to be the results of multiple addition of polyynes chains and their chemical interaction with solvent.
