Okamoto K., Muroya Y., Kozawa T.. Formation of radical cations of para-substituted polystyrenes in dichloroethane by electron beam pulse irradiation. Chemical Physics Letters 884, 142558 (2026); https://doi.org/10.1016/j.cplett.2025.142558.

Transient absorption measurements were conducted on para-substituted polystyrene (PS) derivative radical cations formed in 1,2-dichloroethane using pulse radiolysis. While most PS radical cations are neutralized within microseconds, the poly(4-methoxystyrene) (PMOS) radical cation has a remarkably extended lifetime (t1/2 = 680 μs), which is three orders of magnitude longer than that of PS. This stability is attributed to the formation of stable counterion pairs between the multimer radical cation (where holes are delocalized across multiple phenyl groups) and the Cl− ions. Furthermore, the impact of substituent size on the formation of multimer radical cations in these PS derivatives was examined.
