Structural study of vapour phase deposited 3,4,9,10-perylene tetracarboxylicacid diimide: Comparison between single crystal and ultra thin films grown on Pt(100)

Organic Nanoclusters on Inorganic Nanostructures for Tailoring the Emission Properties of Organic Materials

“…Strong (020) peaks were observed in PTCDI powder, film, and nanostructures grown at high temperature, in good agreement with the previously reported monoclinic PTCDI lattice structure. [20] A. M.-C. Ng et al/Organic Nanoclusters on Inorganic Nanostructures The films deposited at room temperature exhibited more broad and less intense peaks with very small shift compared to nanostructures deposited at high temperature and powder samples, in agreement with previous observations on other perylene dyes and indicating that no significant change in the crystal structure is found for crystalline samples. [21] On the other hand, no peak was found for the nanostructures grown in the low-temperature region, which confirmed that they were amorphous, in agreement with the SAED result (data not shown).…”

Self‐Assembled PDINH Supramolecular System for Photocatalysis under Visible Light

“…The nominal length between two adjacent H-bonded PDI at the longitudinal direction is reported to be 1.402 nm, and the width of the PDI molecule is reported to be 0.92 nm. [37] As a result, the first strong (020) peak [38] in Figure 1A (d-spacing of 7.35 Å) can be assigned to half of PDINH molecule length at the longitudinal direction. [33] The diffraction peak (d-spacing of 4.46 Å) can be attributed to half of PDINH molecular length at the transversal direction, [37] while two peaks emerged at high diffraction angles (d-spacing of 2.21 and 1.97 Å) can be assigned to lengths of hydrogenbond [39] or edge-to-edge distances between two adjacent PDINH molecules at the longitudinal and transversal directions.…”

N‐Type Self‐Assembled Monolayer Field‐Effect Transistors and Complementary Inverters

“…The π -π stacking of the aromatic cores leads to parallel stacks with a typical distance of 0.36 nm. [23][24][25] where the aromatic chains are arranged perpendicular to the substrate surface. However, the stacks arrange themselves in twisted columns without long range order.…”
