  Oligo(3,6-phenanthrene ethynylenes): Synthesis, Characterization, and Photoluminescence

  摘要：

  A series of highly fluorescent, oligo(3,6-phenanthrene ethynylenes) (F1-F7) were synthesized, and their photophysical behavior was systematically investigated. They emitted light with highly emissive quantum yields, up to 0.92. Emissive wavelengths of these compounds relied on the number of phenanthrene blocks existing in the oligomers. Red-shifted emissions were observed as the number of phenanthrenes increased. On the basis of theoretical calculations, helical structures could be formed for F4-F7, indicating that the excimer emissions might be observed for F4-F7 due to the intramolecular pi-pi stackings of phenanthrenes in the helical structures. However, excimer emissions were only observed for F5-F7 in dilute cyclohexane and for F6 and F7 in dilute methylene chloride, respectively. No excimer emission was observed for F4-F7 in dilute tetrahydrofuran due to the degree of solvation.

  ABSTRACTThis manuscript investigates the possibilities to obtain helical conjugated polymers following a controlled chain‐growth polymerization mechanism with external initiation. Attempts to prepare poly(3,6‐(9,10‐di(octyloxy))phenanthrene)s with the existing chain‐growth mechanisms using existing Kumada or Negishi couplings were unsuccessful because of the difficulty to quantitatively prepare the Grignard metathesis reagent starting from the envisaged precursor, namely 3,6‐dibromo‐(9,10‐di(octyloxy))phenanthrene. On the other hand, a Suzuki–Miyaura coupling polymerization using Pd(PtBu3) as the catalyst clearly allows the polymerization to proceed. The reaction conditions were optimized and an in‐depth study with gel permeation chromatography and matrix‐assisted laser desorption ionization time‐of‐flight (MALDI‐ToF) of the underlying mechanisms was performed. Nevertheless, a prolonged chain‐growth mechanism was not achieved for the targeted polymers. © 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2013, 51, 5067–5074
