What is it about?
Molecular field-coupled nanocomputing (molFCN) encodes binary data using molecular charge arrangements. We introduce bend-boosted molFCN, which also uses molecular positioning to encode information. Using 6-(ferrocenyl)hexanethiol cations and density functional theory, we show that this data can be electrically read, making experimental validation feasible. This method could enable molFCN integration with CMOS technology, advancing molecular-scale computing.

Why is it important?
We introduce bend-boosted molFCN, a method that enhances molecular field-coupled nanocomputing (molFCN) by using both charge arrangement and molecular positioning (bending) to encode information. This dual approach is crucial for advancing molFCN, as it overcomes key challenges like detecting molecule charge states and integrating with CMOS technology. Importantly, we demonstrate that information encoded with bending molecules can be electrically read through a molecular junction, paving the way for experimental validation with scanning probe microscopy and potentially enabling practical applications of molFCN in nanoelectronics.
Perspectives
Writing this article was a rewarding experience. The core idea emerged from a brainstorming session with all co-authors, as we tried to answer a central question: How can we demonstrate that molFCN can work using simpler molecules and accessible techniques? In this work, each of the authors contributed directly to the proposal.
