Abstract：In this general scientific report， we summarized our recent progress on chiral supramolecular nanoassemblies： controlled structure and chirality， and related advanced functions， which are obtained since the inauguration of the project. The main issues include the following items： （1）self-assembly of TPPS in organic solvents： from nanofibers to mirror imaged chiral nanorods； （2）a metal ion triggered shrinkable supramolecular hydrogel and controlled release by an amphiphilic peptide dendron； （3）organogelation-controlled topochemical [2+2] cycloaddition and morphological changes： from nanofiber to peculiar coaxial hollow toruloid-like nanostructures； （4）a chiroptical switch based on supramolecular chirality transfer through alkyl chain entanglement and dynamic covalent bonding. Focusing on the issues that we originally assigned in the Plan of the Project， these obtained achievements during 2013 provide us with solid grounds for the performance the future work， which will be carried out in the next year. On the basis of these important result， we believe that advanced materials of tunable functions in terms of multi-level chirality might be developed in our further work.
