Abstract:
Managing the continuous and fast-growing volume of information, the progress of the Internet-of-Things, evolution from digitalization to networking, are huge technological chores. These are highly demanding challenges to Si-based integrated chips that are getting closer to the miniaturization limit with the current top-down approach, opening the gates to a new generation of efficient computing systems that constitute an unsettling step forward. [1] Information processing and computing based on molecules that perform logic operations may play a decisive role in the future of the computer industry.
Molecular logic gates are molecular counterparts of electronic devices [2,3] that, instead of exclusively electrical signals, can be stimulated by diverse chemical or physical input signals producing, many often, optical outputs according to a well-defined logical transfer function. Among the distinct materials reported so far for molecular logics, the Ln3+-based ones appear as a commendable choice, as they can respond to both chemical and physical stimuli, presenting the unique photophysical properties that them quite popular for photonics applications.
In this presentation, we will frame the main of contributions Ln3+-based materials in molecular logic, discussing their potential to integrate future molecular photonic-electronic hybrid logic computing systems. Examples of molecular logic devices using Ln3+ and exclusively physical stimuli, developed in the Phantom-g research group [4] will be revised together with a perspective on the major challenges faced by this field in the years to come.
