Abstract:
This thesis describes the preparation of a new [4+6] porous organic cage, CC12. The new cage has a N2 SABET of up to 946 m2/g, as well as inherent selectivity of gases based on polymorphism. This new porous organic cage has also been reduced and catenated as seen with previous cages. Cages have also been formed from aliphatic diamines, highlighting importance of diamine length in formation of either [2+3] or [4+6] cages (Chapter 3). CC1 has been prepared and reduced in situ to yield RC1, while CC5 was also reduced to produce RC5. These reduced cages have provided a route towards decorated cages via nucleophilic addition/elimination with various acid halides. While no porous materials were observed by addition of bulky or aliphatic groups, this new class of decorated cages presented an excellent basis for further reactions on a 12-armed core, higher than that of POSS alternatives (Chapter 4). Finally, RC1 has been polymerised with bis-acid halides to yield networks with modest N2 SABET of up to 106 m2/g. Decorated cages were also successfully homo-coupled by Yamamoto and polymerised with Sonogashira methods to yield polymers with N2 SABET of up to 150 m2/g. Decorated cages were lastly hyper cross-linked to yield H2 selective polymers and co-polymerised with benzene to yield N2 SABET of up to 954 m2/g (Chapter 5).
