Synthesis and electrical/optical characterization of Amorphorous
Red Fluorophores
Abstract
Maleimide and pyrazine-based fluorophore (structure shown in blow)
with donor-acceptor substituents were designed and synthesized for
tuning fluorescence wavelength into saturated red region. We utilized the
nonplanar conformation that was generated by ortho-substituted aromatic
ring structures for enhancing the amorphous property of the fluorophores.
The absorption and fluorescence of the fluorophores were studied by
UV/Visible and fluorescence spectroscopic methods. HOMO and LUMO
energy levels were derived from cyclic voltametry (CV) data. The glass
transtition temperature(Tg), crystal temperature(Tc) and melting point(Tm)
were determined by DSC (differential scanning calorimeter) and TGA
(thermogravinetric analyzer), respectively., to estimate the amorphous
property and thermal stability of the fluorophores.
