Synthesis and Luminescent Properties of New Oligofluorene Derivatives Containing Various Comonomers

Abstract:

Two kinds of oligofluorenes containing acetylene units are synthesized by Sonogashira coupling reaction. naphthalene and anthracene are co-polymerized with ethynylfluorene, respectively. The structure and properties are characterized using NMR, UV-vis spectroscopy, elemental analysis, DSC and photoluminescence. The oligomers are soluble in common organic solvents such as benzene and easily spin-coated onto glass substrates. The products yield strong emission differing from blue to green-yellow, and red-shift are suppressed with the growth in size of co-monomers.
