The Molecular Structural Arrangement of a Thin Film of Lead Phthalocyanine Crystals

These figures show phthalocyanine crystals, which are commonly used in organic light-emitting displays, and in dye-sensitized solar cells. The four-leaf structure surrounding the metal atom at the center of the molecule can be clearly observed.

Atomic Defects in Polydiacetylene Crystals

Observations were made of polydiacetylene crystal surfaces, cleaved in air. If the terrace observed in the wide-area image (in the figure at left) is enlarged, individual PTS (para-toluenesulfonate) side chains lined up at 0.5 nm intervals can be observed along the main diacetylene chain, running at 0.75 nm intervals parallel to the b-axis. The fact that an atomic defect is visible is evidence that the image is of an actual space, not a FFT image of periodicity.
