Competition between Exceptionally Long-Range Alkyl Sidechain Ordering and Backbone Ordering in Semiconducting Polymers and Its Impact on Electronic and Optoelectronic Properties

ADVANCED FUNCTIONAL MATERIALS, 29(5).

By: J. Carpenter n, M. Ghasemi n, E. Gann*, I. Angunawela n, S. Stuard n, J. Rech*, E. Ritchie*, . Brendan T. O'Connor n ...

author keywords: molecular design; organic electronics; polymer crystals; semiconducting polymers; sidechains
TL;DR: The observed influence of ordering between the moieties implies that improved molecular design could produce synergistic rather than destructive ordering effects and should greatly improve the coherence length of backbone ordering and thereby improve electronic and optoelectronic properties such as charge transport and exciton diffusion lengths.

The Role of FRET in Non-Fullerene Organic Solar Cells: Implications for Molecular Design

JOURNAL OF PHYSICAL CHEMISTRY A, 122(15), 3764–3771.

By: B. Gautam n, R. Younts n, J. Carpenter n, H. Ade n & K. Gundogdu n

TL;DR: It is shown that when charge transfer and exciton transfer processes are both present, the coexistence of excites in both domains can cause a loss mechanism and excitons in low-bandgap material should have a relatively long lifetime compared to the transfer time of exciton population in the larger bandgap acceptor domains.
