Triptycene Derivatives: Sythesis, Structure And Their Properties

Triptycene and its derivatives have attracted much attention during the last twodecades because of their unique three-dimensional rigid structures and highly active spoton the benzene ring and been found to have wide potential applications in molecularmachines, supramolecular chemistry and material chemistry. In the dissertation, synthesis,structure of the novel triptycene derivatives and their properties were studied. The majorconclusions are as follows:（1） A series of three-dimensional nanograrhenes2-24,2-25,2-26,2-27and2-28wereefficiently synthesized through a series of reactions from monoiodotriptycene andtriiodotriptycene, and their structures were characterized by NMR, MS spectra and X-rayanalysis. It was found that2-28could assembly into organic porous architectures in thesolid state, in which C-H….Ï€ interactions play an important role. Moreover, the imagingof the nanoparticle consisted of2-26and F68was also studied, it was found that thenanoparticle could be efficiently incorporated into the cells and generated greenfluorescence when excited at the wavelength of488nm, which supply a basis on theapplication of fluorescent probe.（2） A series triptycene-based microporous polymers were synthesized and theirstructures were determined by NMR, FT-IR, FSEM and TEM analysis. We had studiedtheir sorption in N₂, H₂and CO₂, which showed they had high BET surface （the highest isup to1990m2g-1）because of largely internal microporous structure. Moreover, they alsohad high adsorption quantity （the highest is up to1.90%and18.20%, respectively） whichindicated their regnantly potential application in porous materials.
