Description

<jats:title>ABSTRACT</jats:title><jats:p>We measured the surface free energy of a substrate by transmission electron microscopy (TEM) using sub-millimetre-sized inkjet droplets. By employing two types of TEM grids with different surface free energies, we investigated the relationship between the surface energy and the patterns of an organic solution dried on the grids. We confirmed that the generation of the porphyrin hexamer [(H<jats:sub>2</jats:sub>PAC<jats:sub>15</jats:sub>)<jats:sub>6</jats:sub>TPh] patterns was affected by the surface free energy of the TEM grid.</jats:p>
