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. To …

Understanding the Ultrafast Crystallization Kinetics of Donor–Acceptor Semiconducting Polymers

J. Tent-Pérez, F. Blanco-Vázquez, J. L. Olmedo-Martínez, A. Peinador Veiga, M. Sanviti, M. Prada-Cortés, A. Curé, E. Solla, B. Mundet, C. Aumaître, X. Rodríguez-Martínez, R. Demadrille and J. Martin, J. Am. Chem. Soc., 2026, 148, 35694–35704. The crystallization of donor–acceptor semiconducting polymers occurs on subsecond time scales at elevated temperatures (>300 °C), preventing a rigorous …

On the impact of selective donor:acceptor structural ordering in PBDB-T:ITIC organic solar cells

X. Rodríguez-Martínez, S. Marina, A. Harillo-Baños, M. Campoy-Quiles and J. Martin, J. Mater. Chem. C, 2025, 13, 13776–13786. The bulk heterojunction (BHJ) is the standard configuration of the photoactive layer in single-junction organic solar cells. Therein, electron-rich (a donor polymer) and electron deficient (a small molecule acceptor) organic semiconductors are intimately blended to form a …
