Near‐Infrared Dichromic Fluorescent Carbocyanine Molecules

Bilingual fluorescent molecules: An array of asymmetric carbocyanines capable of dual fluorescence emissions in the near-infrared region is described (see image). The fluorescent molecules are robust in different pH and solvents. Additionally, each fluorescence peak possesses a distinct fluorescence lifetime. These properties are retained after conjugation of the dyes with small bioactive peptides.
