Next, bending tests were conducted to measure the Young's modulus in the longitudinal direction. Since Young's modulus measured by bending test is a small fraction in the dataset, measurement results may differ from the LASSO trends. Crystals with larger Young's moduli in the thickness direction tended to have smaller Young's moduli in the length direction (Figure ). This can be attributed to the anisotropy of organic crystals. A large Young's modulus in the thickness direction indicates strong intermolecular interactions in that direction. When strong interactions form in one direction, and given that similar molecules are used in all crystals, weaker interactions such as CH-π interactions and van der Waals forces become the main intermolecular interactions in other directions, thus explaining the smaller Young's modulus. It is also noted that the standard deviation of the bending test is larger than that of nanoindentation, because the bending tests calculate Young's modulus from macroscopic deformation against load.
