Fig. 1. (a) On-surface synthesis of singly Por-capped GNR hybrids 1(Zn)n from Por 3(Zn) and DBBA. (b) STM image after the surface reaction at 350 °C on Au(111) (sample bias Vs = −0.5 V, tunneling current It = 30 pA) showing formation of 1(Zn)0 (dashed yellow circle), 1(Zn)1 (dashed red circle), and 1(Zn)2 (dashed green circle) GNR–Por hybrids. (c) nc-AFM images of GNR–Por hybrids 1(Zn)0, 1(Zn)1, and 1(Zn)2 showing the bond-resolved structures (Setpoints: −5 mV, 150–200 pA. oscillation amplitude: ∼80 pm). Scale bar: 5 Å.
