From the analysis of UV/vis absorption, emission, and excitation of emission spectra of all-trans-alpha,omega-tetra-tert-butylpolyenes with six and seven double-bonds (3,14-di(tert-butyl)-2,2,15,15-tetramethyl-3,5,7,9,11,13-hexadecahexaene (ttbP6), and 3,16-di(tert-butyl)-2,2,17,17-tetramethyl-3,5,7,9,11,13,15-octadecaheptaene (ttbP7)) it is concluded that these hydrocarbons do not exhibit dual S-1/S-2 fluorescence, as could be inferred from the work of Christensen et al. [J. Phys. Chem. A 2008, 112, 12629-12636]. The spectral data for ttbP6 and ttbP7 display a unique fluorescence from their S-1 states.
