Full characterization of nanostructured
organosilicon luminophores NOL4 and NOL5 based on
the donor 2,2’-bithiophene and acceptor 1,4-bis(2,2′-
bithiophene-5-yl)benzene units in dilute solutions and
thin films by UV-Vis spectroscopy, DSC, TGA and X-ray
techniques was reported. It was found that usage of
these molecules as dopants (10–20 wt%) to the electroactive
polyfluorene host in organic light-emitting devices
(OLEDs) leads to the efficient spectral long wavelength
shifting of the electroluminescence and an increase of the
OLED performance as compared to the devices based on
pristine polyfluorene, NOL4 and NOL5.
