Description
Elias Ciekalski and Henry Dube present in 2026 a molecular switch that flips under near-infrared light reaching 900 nanometers, deeper than any rival of its kind. Light that red avoids damaging tissue and leaves the visible range free for display colors. Their switch, built around a fused sulfur dye core, answers directly to that gentle light.
Flipping gave high yields of each form, held steady with heat, and swung color dramatically from pale green to deep blue. Set into a common commercial polymer, the switch accepted writing with invisible light in fine spatial detail. Handheld flat and three-dimensional displays plus optical memories were demonstrated. Reversible, damage-free inscription with unseen light is the headline advance.
