Thermal-mediated modulation of binary supramolecular self-assembly from phase separation to co-crystallization at the liquid-solid surface.

ABSTRACT: Significant research in materials chemistry has focused on the design and fabrication of organic materials and their self-assembled architectures for a wide range of applications, such as organic transistors, photovoltaic cells, and surface functionalization, to name just a few. For binary supramolecular systems, however, the increased complexity that involves hetero-molecular interactions often leads to challenges, for instance, undesired phase segregation. Using scanning tunnelling microscopy (STM), we show that thermal activation (from 25 °C to 60 °C) can drive a transition from phase separation to thermodynamically stable co-crystallization for a host-guest system comprising trimesic acid and a tetrathiafulvalene derivative. Our STM data revealed that the co-crystals varied from the ch
