Shape transition of liquid crystalline oligomers by thermal oligomerization. (a) Schematic images of thermal oligomerization procedure. (b) Shape transition of liquid crystalline oligomers from spherical to branched and fibrous shapes visualized by optical microscopy (i–iv) and local connected fractal analysis (v–viii) against thermal oligomerization time of (i,v) 6 h, (ii,vi) 12 h, (iii,vii) 18 h, and (iv,viii) 24 h. (c) Diameter (■) and width (▼) of nematic liquid crystalline oligomers against thermal oligomerization time. (d) Fractal dimension (●) and lacunarity (▲) of nematic liquid crystalline oligomers against thermal oligomerization time.
