Synthesis and Optical Properties of Triphenylene-Based Donor-Donor and Donor-Acceptor Conjugated Polymers: A Comparative Study

Figure 11

Absorbance-corrected fluorescence emission (excited at the corresponding absorption maximum) spectra of P1 and P2 as dilute solutions in mixed hexane/EtOH solvent of different volume ratios. Note that P2 has poor solubility in hexane, and the upper, clear portion of a saturated P2 solution in hexane was collected and used as the stock solution.
