The author of the article were Li, Jincai; Richardson, Joseph J.; Ejima, Hirotaka. The article conveys some information:
Poly(4-thiostyrene), a historically challenging to synthesize polymer, is synthesized herein via a feasible three-step protocol. Based on the newly developed protection-deprotection strategy, the precursor polymer containing thiomethyl groups is deprotected using Li/naphthalene to yield poly(4-thiostyrene) after acidification. This newly developed procedure is crucial for preventing crosslinking of the thiol groups and therefore the resulting polymer is soluble in common organic solvents (e.g., chloroform, tetrahydrofuran) and can be stored long-term, which has been challenging to accomplish over the past 60 years. The successful synthesis is confirmed by various characterization techniques including NMR, Fourier-transform IR spectroscopy, and Raman anal., which collectively are new and useful data that have generally been unavailable in previous reports. This work provides a robust approach for synthesizing this promising polymer and offers a new route to investigate thiol-containing polymers. In the experiment, the researchers used many compounds, for example, Methyltriphenylphosphonium bromide(cas: 1779-49-3Recommanded Product: Methyltriphenylphosphonium bromide)
Methyltriphenylphosphonium bromide(cas: 1779-49-3) is a lipophilic molecule with a cation allowing for it to be used to deliver molecules to specific cell components. Also considered an antineoplastic agent.Recommanded Product: Methyltriphenylphosphonium bromide
