Abstract:

Fluorescence emission spectra are reported for phenanthro[5,4,3,2efghil]perylene, dibenzo[cd,k]naphtho[8,1,2fghi]perylene, benzo[b]perylene, dibenzo[e,ghi]perylene, and benzo[a]naphtho[8,1,2cde]-naphthacene dissolved in various organic solvents. Results of these measurements are used to screen PAHs for potential solvent polarity behavior. Of the five PAHs studied, only phenanthro[5,4,3,2efghi]perylene exhibited probe behavior, as evidenced by selective emission intensity enhancement of band I with increasing solvent polarity.
