Recently, polymerization science has assumed an increasing relevance in many applications, including orthopedic and dental biomaterials. Current technologies are based on the use of photochemically reactive systems, which are suited to absorb light to produce primary radical species capable of initiating polymerization. Acylphosphine oxides and acylphosphonates are known to be very effective photoinitiators for various unsaturated polymeric systems. The high reactivity observed was ascribed to the phosphinyl and phosphinoyl radicals generated. Because of the poor qualities of other initiators, we examined new routes to synthesize acylphosphine oxide initiators to achieve compatibility with aqueous media and improved performance. The preparation and …

The Selective Synthesis Of Oxacalix[6]Arenes And The Exploration Of Azacalix[N]Arenes, W. Christian Crannell
The Selective Synthesis Of Oxacalix[6]Arenes And The Exploration Of Azacalix[N]Arenes, W. Christian Crannell
Honors Theses
Calix[n]arenes, cyclIc molecules composed of "n" benzene rings meta-linked by a methylene to form a macrocycle, are very prevalent jn the literature and enjoy a wide range of applications. However, the oxygen bridged and nitrogen bridged systems, oxacalllx[n)arenes and azacalix[n]arenes, respectively, are far less common because they are synthetically challenging. Furthermore, the selective synthesis of oxacalix[6]arene systems has not previously been well documented, but the systems can now be accessed in a facile approach disclosed here. The insight and knowledge gained from the synthesis of oxacalix{6]arenes has provided a foray into the synthesis of azacalix[nlarenes.
