"This thesis is focused on the synthesis and modification of [2+3] organic imine cages based on 2,7,14-triaminotriptycene. Many porous cage compounds have been synthesized based on triptycene precursors because of its rigid 3D skeleton and a D3h symmetry. However, modifying the cage compounds with functional groups which may empower the cages is still challenging. \r\nIn general, post-synthetic modification in pre-synthesized cages and modification of molecular precursors are two main strategies to introduce functional groups into cage compounds. By modifying aldehyde building blocks, ten different side-chains were introduced to the [2+3] terphenyl imine cages. Solubility in organic solvent was improved for all these new cages compared with the unfunctionalized one. Among these cages, the perfluorobutyl chain modified cage exhibits specific surface area up to SABET = 588 m2/g and high Henry selectivity SSF6/N2 = 107 for sulphur hexafluoride over nitrogen, which shows a potential application in the separation of sulphur hexafluoride. \r\nBesides the aldehyde building blocks, a new amine building block was constructed by triaminotriptycene and pyridine dicarbonyl dichloride. This new amino building block was used to react with a series of salicylaldehydes with different distance between the aldehyde groups, and the results prove topologies of cage can be affected by the length of the aldehyde precursors. \r\nIn the third part, through a post-synthetic modification strategy, a carbamate cage was synthesized after two steps based on a [2+3] imine cage (formed by triaminotriptycene and bisphenyl salicylaldehyde). This carbamate cage exhibits high pH stability from pH =-1 to 14 which is proved by NMR spectra, SEM and gas sorption experiments. This is one of the most stable cage compounds reported so far"^^ .
