A core/sheath structure is fabricated by decorating single‐crystal organic nanowires with H 2 O 2 ‐reactive peroxalate ester, as reported by J. Yao, Y. S. Zhao, and co‐workers on page OP194 . The shell of the nanocable is highly sensitive and selective to the H 2 O 2 molecules, demonstrated by the generation of chemiluminescence on exposure to H 2 O 2 vapors. The cable‐like optical waveguide sensing platform can rapidly and selectively monitor H 2 O 2 vapors through the amplified optical variation across the wire waveguiding, showing that a single nanocable is very promising for developing optical probes to detect individual responses on‐chip.
