Diphenylacetylenes having both a trimethylsilyl group and an alkyl group at para positions [Me 3 SiC 6 H 4 C^CC 6 H 4 R; R ΒΌ Et (1a), n-Bu (1b), t-Bu (1c), n-C 8 H 17 (1d)] and having only an alkyl group [PhC^CC 6 H 4 R; R ΒΌ n-Bu (1B), n-C 8 H 17 (1D)] were synthesized and then polymerized with TaCl
Phosphazene polymers are unique materials in that series of materials can be synthesized with a uniform backbone structure while varying the pendant group speciation. The result of this variation is that the physical properties can be controlled through adroit selection of pendant groups. In this wo
