Fig. 1. On-surface synthesis of pentalene-bridged bisanthene polymers.

Fig. 1

a Scheme of the reaction sequence of 4BrAn precursor after being deposited on Au(111), annealed to 500 K to obtain polymer 1, and annealed up to 700 K to only produce irregular defective polymers (see Supplementary Fig. 1). b Scheme of the reaction sequence of 4BrBiA precursor after being deposited on Au(111), annealed to 500 K to obtain polymer 2, and annealed to 650 K to result in polymer 3. c STM topographic overview (left panel; 0.03 V, 0.1 nA) and detailed nc-AFM/STM constant height images (right panels) of cumulene-linked bisanthene polymers (2). d STM topographic overview (left panel; 0.05 V, 0.1 nA) and detailed nc-AFM/STM constant height images (right panels) of pentalene-bridged bisanthene polymers (3).
