Growth of a thin film with other conjugated molecules containing Br groups (IMAGE)
Caption
(a–c) Optical, SEM, and AFM images, respectively, of a grown film transferred to a SiO2/Si substrate using C24H4O2Br2 as the source. The inset in (a) shows the molecule structure of the sample. (d–f) Optical, SEM, and AFM images, respectively, of a grown film transferred to a SiO2/Si substrate using C24H12Br2N4 as the source. The inset in (d) shows the molecule structure of the sample. (g, h) XRD patterns of thin films synthesized from C24H4O2Br2 and C24H12Br2N4 as sources, respectively. (i, j) XPS spectra, showing no Br groups in the corresponding thin films (red) from C24H4O2Br2 (blue) and C24H12Br2N4 (blue) sources, respectively.
