Abstract

Abstract: Stable polyyne chains terminated with biphenyl end groups (α, ω-biphenylpolyynes) were synthesized in a single step through a simple procedure by using the Cadiot-Chodkiewicz reaction conditions. The α, ω-biphenylpolyynes were separated through HPLC analysis and identified by means of their electronic absorption spectra. The α, ω-biphenylpolyynes were studied by FT-IR and Raman spectroscopy and the spectral interpretation was supported with DFT calculations. A peculiarly low reactivity of α, ω-biphenylpolyynes with ozone was observed. Graphical abstract: Image
