Abstract
We report the study of supramolecular assembling from both experimental and theoretical points of view. A scanning tunneling microscope (STM) and the Johnson–Mehl–Avrami (JMA) equation were, respectively, used to reveal and to explain the “STM-directed” self-assembling of p-terphenyl-3,5,3′,5′-tetracarboxylic acid (TPTC) at the liquid–solid interface. The Avrami index helps in providing significant information regarding the surface supramolecular crystalline framework. It also helps us to calculate the domains of crystal growth, to distinguish the crystal development to be homogenous or heterogeneous, as well as to identify the dimension of the crystal growth. The JMA equation was also used to evaluate whether (i) the close-packing crystal of TPTC can develop into a single crystal or (ii) the porous networks of TPTC may hinder the close packing to form during its progression.
