Local Order Is Not Enough: Synthetically Accessible Polymers Reveal the Role of Side-chain Branching Point in Organic Solar Cell and Transistor Performance
M. Rimmele, X. Rodríguez-Martínez, Z. Qiao, K. Wei, A. V. Marsh, J. Panidi, N. Gasparini, J. Martin and M. Heeney, Adv. Electron. Mater., 2026, 12, e70521. Side-chain engineering provides a powerful strategy for controlling the microstructure and electronic properties of conjugated polymers, but improved crystalline order does not necessarily translate into enhanced device performance.
