Fabrication of luminescent perylene bisimide nanorods

Optical and Electrical Properties of New Perylene Diimide Thin Films

“…Perylene diimides 1-6 were synthesized as reported elsewhere. 21,22 Powder x-ray diffraction (XRD) was measured in reflection mode (CuK a radiation) by use of an X'pert Pro x-ray diffractometer. SEM measurements were performed by use of an Hitachi scanning electron microscope.…”

Self-assembly, optical and electrical properties of five membered O- or S-heterocyclic annulated perylene diimides

“…When placed in dichloromethane and subjected to modest potentials, these chromophores undergo two quasi-reversible reductions and one quasi-reversible oxidation. These two quasireversible reduction processes originate from successive reduction of the imide groups to give a radical anion (O-PDI -or S-PDI -) in the first reduction step and a dianion (O-PDI 2-or S-PDI 2-) in the second step [5]. The first reduction process increases the electron density on the carbonyl oxygen of one imide group.…”

Analyte-induced spectral filtering in femtosecond transient absorption spectroscopy

“…Absorption spectra with narrow lines are found in many bio-molecular systems; for example in proteins like rhodopsin that are responsible for vision processes, and in porphyrins involved in photosynthesis [8,9]. Narrow absorption features are also common in photochemical systems like transition metal complexes used for photocatalysis and solar cells [10][11][12][13][14], and have been reported for semiconductor bulk materials and nanostructures as well [15][16][17][18]. TA measurements on semiconductors at the band edge are another example affected, since partial pulse overlap with a sharp absorption edge will lead to a similar effect.…”
