Allenes, one of the compounds with cumulative double bonds, are attracting much interests due to the characteristics of their twisted π-conjugated bonds. Several allenes were synthesized to characterize their electronic features by their ground-state absorption, transient absorption and emission spectra to be found that they increase conjugation length in the excited state due to their conformational change. Photophysical process and active species were determined by laser flash photolysis and electron beam pulse radiolysis to find that intramolecular charge transfer of an allene is induced upon electron beam irradiation.
