Supramolecular materials can be tailored from precisely designed small molecules by bottom-up approach under the control of directional noncovalent interactions.[1] The morphologies and structures of self-assemblies play an important roles in define their properties and applications.[2] Recently, we found that thiophene decorated disk-shaped hexapyridylbenzene (THPB) derivatives, self-assemble to give crystalline nanoobjects in solution which induced by silver ion.Interestingly, the morphologies and structures of nanoobjects showed step-by-step changes in response to change in the amounts of silver ion (Figure 1).Details of the self-assembling behaviors of these THPBs will be reported.
