White light emitting molecular logic gates

Area of Science:

• Materials Science
• Photochemistry
• Molecular Sensors

Background:

• White light emitting (WLE) materials are crucial for displays and lighting, characterized by luminescence from 380 to 700 nm.
• Designing molecules for white light emission is challenging due to Kasha's rule, but new photophysical mechanisms like ESIPT, TICT, VIE, and AIE have advanced the field.
• Molecular sensors with white light emission capabilities are rare, especially those performing logic-based sensing for multiple analytes or properties.

Purpose of the Study:

• To review the rare field of molecular sensors that exhibit white light emission and possess logic-based capabilities.
• To introduce fundamental concepts of Boolean logic for a non-expert audience.
• To survey existing molecular sensors and logic gates that emit white light for addressing societal challenges.

Main Methods:

• Literature review of photophysical mechanisms enabling white light emission (ESIPT, TICT, VIE, AIE).
• Introduction to Boolean logic principles.
• Survey and analysis of molecular sensors and logic gates with white light emission properties.

Main Results:

• Significant progress in understanding photophysical mechanisms for designing WLE molecules.
• Identification of specific photochemical concepts (ESIPT, TICT, VIE, AIE) contributing to WLE.
• Highlighting the rarity and potential of logic-based molecular sensors emitting white light.

Conclusions:

• Logic-based molecular sensors emitting white light represent a promising frontier in materials science.
• These advanced materials offer potential solutions for complex societal challenges through multi-analyte sensing.
