Details of the effect of elevated temperatures on the c-P40 rings in the presence of co-deposited TIPB. (a) STM image showing c-P40 rings after annealing the Au(111) surface to ~105 °C. Rings are broken in several places and rings within stacks have been laterally displaced (Iset = 30 pA, V = −1.8 V). (b) STM image of c-P40 rings on Au(111) after annealing to ~115 °C. Broken porphyrin chains inside and outside rings are indicated (white arrows), (Iset = 20 pA, V = −1.8 V). (c) STM overview image showing several large domains of co-deposited contaminant material on surface (Iset = 20 pA, V = −1.8 V). (d) Close up of area in (c) showing various domains of contaminant material (Iset = 20 pA, V = −1.8 V).
