The fluorescence and Raman spectra of bis(1-methylpyrrol-2-yl)arene de
rivatives are reported in order to obtain information about the conjug
ation in poly(bis-1-methylpyrrolylene-alt-arylene)s. The luminescence
and the frequency dispersion were influenced by electronic effects and
steric demands. Photo polymerization is observed during light irradia
tion. This effect is most pronounced in case of the 2,5-bis(1-methylpy
rrol-2-yl)furan.
