Synthesis of a Conjugated Ladder Polymer for Application in Direct Writing.
… discovery of electroluminescence in conjugated polymers in 1990, electro-optic devices such as light emitting diodes, flat panel all polymer displays, and lasers have received a great deal of attention. Greater conjugation in these pi-electron systems leads to enhanced fluorescence and smaller …

The design and synthesis of linear and macrocyclic Poly(para-arylene)s
… synthesis of poly(para-arylene)s via the post polymerization functionalization of a completely soluble and easily accessible precursor polymer, utilizing the metal-catalyzed [2+2+2] reaction. We expect that this versatile strategy could lead to new and interesting PPP derivatives. In Chapter 3, …

Sterically Crowded Copolymers Based on Functionalized Stilbenes
… were prepared via a "protected" precursor polymer strategy. The polyelectrolyte precursors readily dissolved in organic solvents and were characterized by 1H NMR, SEC, TGA, and DSC. The polyelectrolytes were obtained via simple deprotection chemistries. The use of different …
