    • Polymer 2 was found in this case to have an absorption maximum at 505 nm, in contrast to 494 nm in Barton's studies. This slight discrepancy can likely be ascribed to different solvents.

    • 2-Ethynyl-1,1-dimethyl-3,4-diphenyl-5-(phenylethynyl)silole and 2-chloro-5-ethynyl-1,1-dimethyl-3,4-diphenylsilole were also found to be unstable under the cross-coupling reaction conditions and decomposed upon prolonged storage.

    • This is not a general limitation: solubility can be modulated by the use of larger 1,1-diatkyl siloles.
