Abstract
Fluorescence emission spectra are reported for benzo[rst]dinaphtho[2,1,-8,7defg;2′1′8′,7′ijkl]pentaphene, dibenzo[a,rst]naphtho[8,l,2cde]pentaphene, dibenzo[fg,ij]pentaphene (also called dibenzo[b,n]perylene), dibenzo[de,kl]naphtho[l,2,3,4rst]pentaphene, dibenzo[h,rst]pentaphene, pyranthrene, tetrabenzo[de,hi,op,st]pentacene, and dinaphtho[2,l,8,7de fg;2′,l′,8′,7′opqr]pentacene dissolved in various organic solvents. Results of these measurements are used to screen PAHs for potential solvent polarity behavior. Of the eight PAHs examined, only dibenzo-[h,rst]pentaphene exhibited probe behavior as evidenced by selective, systematic emission intensity enhancement of band I with increasing solvent polarity.
