21. 3, resulted in very reproducible data.
22. 3 indicated that by mixing the Por oligomer and CP, somewhat larger assemblies with a high aspect ratio assignable to the Por/CP composite exist in solution (see the Supporting Information). At the present stage, we can not fully rule out the competitive association system (the intersected model) depicted in Figure 4b; however, we infer that the formation of the composite as illustrated in Figure 4a is more likely.
23. The assemblies of the composites may form a mesophase or organogel; however, we could not observe gelation phenomena under the conditions used and liquid crystalline phases.
