Liquid crystalline phase and crystals formed during the polycondensation of nCAp with nTGp. (A) Liquid crystalline domain formed by polycondensation of 5 mM nCAp with 5 mM nTGp in the presence of 30% PEG 6000 after 48 h of reaction. Scale bar is 10 μm. (B) Spherulites observed during nCGp polycondensation after 48 h of reaction. Scale bar is 10 μm. (C) Ribbon-like crystals observed in the reaction mixture at late reaction stages (here 72 h) in polycondensation of 10 mM nCAp with 10 mM nTGp under polarized light (the length of the scale bar is 50 μm). (D) The same crystal under the white light.
