Spectrally Tuned Floating‐Gate Synapse Based on Blue‐ and Red‐Absorbing Organic Molecules for Wavelength‐Selective Neural Networks and Fashion Image Classifications (Adv. Funct. Mater. 13/2026)

Wavelength-Selective Neural Networks In their Research Article (10.1002/adfm.202525060), Seyong Oh, Chung Whan Lee, Yun-Hi Kim, Hocheon Yoo, and co-workers present a spectrally tuned floating-gate synapse that shows wavelength-selective optical plasticity. This enables neuromorphic vision capable of distinguishing multicolor stimuli. The illustration highlights optical pathways for different wavelengths and fashion image recognition through synaptic learning, presenting how optoelectronic behavior integrates with color-specific pattern classification.
