In article number 2204839, Chi-Ming Che and co-workers describe a photonic logic gate device based on supramolecular heterostructures made by phosphorescent Au, Cu, Pt, and Pd complexes. The photonic logic gate operation is realized by an optical waveguiding effect and energy transfer among the different building blocks. These photonic logic gates have high emission anisotropy, low optical waveguiding loss, and continuously varied emission colors ranging from blue to near-infrared spectral regions.
