TL;DR

This paper introduces a pseudo-code representation for molecular programming to design molecular electronics devices, focusing on organic molecule-based rectifying diodes and logic gates like AND. It establishes a generic computational model to formalize molecular computation, enabling systematic design and simulation of molecular-scale logic circuits using a high-level programming abstraction.

ABSTRACT

This research paper is proposing the idea of pseudo code representation to molecular programming used in designing molecular electronics devices. Already the schematic representation of logical gates like AND, OR, NOT etc.from molecular diodes or resonant tunneling diode are available. This paper is setting a generic pseudo code model so that various logic gates can be formulated. These molecular diodes have designed from organic molecules or Bio-molecules. Our focus is on to give a scenario of molecular computation through molecular programming. We have restricted our study to molecular rectifying diode and logic device as AND gate from organic molecules only.

Motivation & Objective

• To develop a standardized pseudo-code abstraction for molecular programming to streamline the design of molecular electronic devices.
• To address the lack of a high-level programming interface for molecular-scale logic circuits and rectifiers.
• To enable systematic formulation and simulation of molecular logic gates using a formalized computational model.
• To focus on organic molecules and bio-molecules as building blocks for molecular diodes and logic devices.
• To establish a foundation for molecular computation through a structured programming paradigm applicable to molecular electronics.

Proposed method

• Design a generic pseudo-code model to represent molecular logic operations such as AND, OR, and NOT using molecular components.
• Define molecular rectifying diodes using organic molecules as the fundamental building blocks for unidirectional current flow.
• Map logical gate behavior (e.g., AND gate) to molecular configurations through algorithmic abstraction.
• Use a high-level programming syntax to describe molecular device assembly and function, abstracting from physical quantum mechanics.
• Integrate schematic representations of molecular devices with executable-like pseudo-code for design and verification.
• Restrict the model to organic molecules and bio-molecules to ensure chemical feasibility and compatibility with existing synthesis methods.
