Photoemission investigations of quasi-one dimensional materials reveal the unconventional electronic properties of these systems. The normal state spectra are incompatible with a Fermi liquid description, and exhibit features consistent with the Luttinger liquid scenario, which describes correlated fermions in 1D. Specific surface effects, and the tendency to defect-induced localization in these systems, may considerably influence the measured spectral properties.
