Characterization of thermally evaporated 1,8-diacetoxy-9,10-anthraquinone films

Characterization of alkali halides doped 1-(2-methoxy benzyloxy)-8- hydroxy-9,10-anthraquinone films for photovoltaic applications

“…Thus, these films exhibited semiconductor like temperature dependence in experimental temperature range studied (290-403K). Observations reveal that resistivity of LiCl and LiBr doped films decreases by an order of 10 3 as compare to ligand films, 6 whereas NaCl, NaBr and KBr treated films do not show any appreciable decrease in resistivity. These results may be attributed to the fact that the presence of Li + cation in the cavity makes the polarization of the bonds of Aq, which results in decrease in resistivity and hence increased conductivity.…”

“…The Aq films has been grown by Hot wall (HW) technique described earlier [6,7] on glass substrates kept at 348 K. Chemical modifications of HW grown films of Aq has been performed by their treatment with one molar solution of LiCl, LiBr, NaCl, NaBr and KBr in distilled water. The doped films were washed with solvent used, air-dried shortly and heated at 323 K for one hour in vacuum of 10 -5 Torr.…”

“…In this paper, we planned to systematically investigate the effect of alkali halides on Aq thin films. We have already reported the growth and properties of Aq thin films [6]. In this paper, electrical and optical properties of alkali halide (LiCl, LiBr, NaCl, NaBr and KBr) doped Aq films has been discussed.…”

Nonvolatile WORM memory devices based on polymethacrylate with azoanthraquinone group

“…Our group has reported a series of memory devices based on the polymers containing the azobenzene group [14]. Here a new -conjugated group, anthraquinone, is to be introduced into the polymer containing azo bond because it is a good charge carrier for the conduction in devices [15,16]. The polymer containing azoanthraquinone group was synthesized and the memory effect of the device based on this single polymer system was investigated.…”
