A new acyl‐functionalized poly( p ‐phenylene) (Ac‐PPP) was synthesized by Yamamoto cross‐coupling and chemically modified to obtain an anthracene‐containing derivative (An‐PPP). The chemical structures of the polymers were confirmed by 1 H‐NMR, 13 C‐NMR, and FTIR spectroscopic analysis. They are fully soluble in common organic solvents and have number‐average molecular weight of 2.70 × 10 3 and 5.26 × 10 3 g mol −1 for Ac‐PPP and An‐PPP, respectively. The optical properties of the polymers were investigated by UV–visible absorption and photoluminescence spectroscopies. A green emission was observed in Ac‐PPP solid thin film and a yellow one in the anthracene‐containing polymer An‐PPP. The optical bandgap values were 3.21 and 3.08 eV for Ac‐PPP and An‐PPP, respectively. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
