| The phenanthrene is a well-known application segment in polymer photochemistry. The introduction of a phenanthrene segment into supramolecular chemistry will show unique spectroscopic character So, we designed three kinds of novel aromatic amphiphiles, consisting of PEO dendron chain as coil and triphenanthrene segment as a rod block. After synthesizing, the resulting amphiphiles were characterized by NMR spectroscopy, elemental analysis and MALDI-TOF, and shown to be in full agreement with the structure. We performed various experiments to investigate self-assemble behaviors in bulk and solution stateswith XRD, POM, DLS and also a specific feature of spectroscopic character by inducing self assembly. One of the these compound was self assembled to cylinderical structure in aqueous solution and was self organized lamella structure in lyotropic state due to the shape of molecules. To further research, LB experiment was performed to investigate nanostructure between air-water interface. |
