Shape‐shifting : The temperature effect on the arrangement of stilbenoid dendrimers on HOPG is presented. A hexagonal nanostructure of SD12 (a stilbene dendrimer) at 16 °C (left picture) is changed into a parallelogram nanostructure after annealing the adlayer at 65 °C (right picture). The results in this research are useful in understanding the phase transition of SD12 , as well as that of metastable complex systems, with temperature.
