Abstract Details

2016, Doctor of Philosophy, Miami University, Chemistry and Biochemistry.
The synthesis of polyurethane dendrimers was achieved with a divergent approach, using different cores and building different generations. Diethylene glycol, triethylene glycol, 2-butyne-1,4-diol and 2-butene-1,4-diol were used as cores to synthesize polyurethane dendrimers by using diphenyl phosphoryl azide. The convergent strategy and the selectivity of the reactions of alkene alcohols on the periphery have been applied to the synthesis of a polyurethane wedges. The first and second generation polyurethane wedges with allyl or pentene peripheries were prepared. The thiol functional group was reacted with an alkene to create first and second generation polyurethane wedges with thiol-ene click periphery. The polyurethane wedges were used to synthesize polyurethane dendrimers. The synthesis of the first and second generation polyurethane wedges with peripheral alkyne groups was achieved with a convergent approach. The first and second generation polyurethane wedges with a pentyne periphery were prepared. The first generation polyurethane with pentyne periphery was useful for click reaction with boronic acid, 4-azidobenzoic acid, and 3-azido-7-hydroxycoumarin. The first and second generation polyurethane wedges with pentyne or triazoles peripheries were used to prepare several kinds of dendrimers.
