Fig. 3. (a) Schematic illustration of the ECL waveguide (ECLW) in single molecular wires of Ir(piq)3 on a patterned ITO electrode; (b) PL and ECL images of single molecular wires of Ir(piq)3 on the ITO electrode in 0.1 M PB solution (pH 7.4) containing 0.1 M TPrA. ECL images were captured at +1.5 V. The exposure time was 60 s. The grayscale variation of PL and ECL along the longitudinal axis of two molecular wires shown in PL and ECL images.
