Figure 2

The polycrystalline thin film were fabricated from a 0.5 wt% diethylbenzene solution at ∼110 °C, (a,d) texture as determined by optical microscopy and (b,e) AFM images. Insets show cross-sectional profiles observed by (a,d) confocal laser scanning microcopy and (b,e) AFM. (a,b) As-coated polycrystalline film and (d,e) after thermal stress at 150 °C for 5 min. (a,d) White bars indicate scale of 20 μm in length. (c) Four d-spacings of Ph-BTBT-10 in crystal and SmE phase in wide- and small-angle regions as a function of temperature.
