| Abstract |
Composites based on dispersion of gold(III) chloride (AuCl3) in 1-nitro-2, 3, 6, 7, 10,
11-hexakis (hexyloxy) triphenylene (HAT6-NO2) have been prepared by using chemical
solution method. The thermal properties and phase transition temperatures of the composites
were determined from differential scanning calorimetric (DSC) method. All DSC curves of
the Au-doped HAT6-NO2 composites show clearing temperature (columnar-to-isotropicliquid
phase transition) close to those of pure HAT6-NO2 matrix. Incorporation of 0.5-
1.0wt% AuCl3 in HAT6-NO2 does not destroy liquid crystal behavior of the matrix. The
photoluminescence (PL) emission spectra (λexcitation = 360 nm) of the composites were taken
in dichloromethane medium. The PL spectra show two emission peaks around 411 nm and
443 nm. Improvement of PL intensity is also observed with addition of gold(III) chloride up
to 1.0wt%. In addition, the UV–visible spectra of the composites have been monitored in
dichloromethane medium. After AuCl3 doping, a broad absorption throughout the visible
region was observed. The main peaks were at about 320 nm and 350 nm due to π→π∗
transition. This wide absorption over the visible region after AuCl3 doping makes the
composites as a potential candidate for photo applications and solar absorber. |
