1 (0.5-5.0 wt%) was dissolved in a medium for sol-gel polymerization: the medium consists of ethanol
(100-1000 mg), TEOS (16-32 mg), water (2-6 mg) and benzylamine (2-6 mg) as a catalyst. The sample
was sealed in a glass tube and left at ambient temperature for 3-10 days.
To prepare TEM sample b, 1 was dissolved in ethanol, and the solution was gelated ethanol after
several minutes. The 1 ethanol gel was taken on Cu grid. Then, 2 wt% OsO4 solution was added on Cu
grid which contained the 1 ethanol gel sample. In TEM sample c, 1 and 2 wt% OsO4 were dissolved in
ethanol. Then, the 1 ethanol gel fiber which adsorbed OsO4 on the gel surface grew up. The 1 ethanol
gel sample was taken on Cu grid. Finally, we observed TEM images of both samples.
