Charge recombination in organic small-molecule solar cells by Jiye Lee.
… of the archetype organic solar cell molecules, copper phthalocyanine (CuPC) and 3,4,9,10-perylenetetracarboxylic bis-benzimidazole (PTCBI). We report the formation of triplet excitons on PTCBI molecules, which may be an important source of recombination loss in CuPC/PTCBI photovoltaic cells. …

Two-dimensional molecular self-assemblies on surfaces studied by low-temperature scanning tunneling microscopy
… surfaces was investigated initially, including copper hexadecafluorophthalocyanine (F16CuPc) and di-indenoperylene (DIP) ultra-thin films on graphite and/or SiO2. To increase the tunability and functionality of the surface-supported nanostructures, robust 2D binary molecular networks, whose …

Silicon-Based Molecular Nanotechnology: Fabrication and Characterization With the Scanning Tunneling Microscope
… organic molecules (e.g., norbornadiene (NBE), copper phthalocyanine (CuPc), and C60) have been isolated. The mechanical, chemical, and electronic properties of these individual adsorbed species are then immediately detected with the STM. For CuPc, the spatial extent of charge transfer from the …

Organic solar cells based on liquid crystalline and polycrystalline thin films
… semiconductors.Discotic liquid crystal (DLC) copper phthalocyanine was investigated as an easily processible building block for solar cells in which ordered molecular arrangements are enabled by a self-organization in its mesophases. An increase in photocurrent and a reduction in series …

Continuous color removal from concentrated dye waste discharges using reducing and oxidizing chemicals: a pilot plant study
… for an azo-based red dye waste concentrate and a copper-phthalocyanine-based dye, Ming Jade, respectively. The soluble copper concentration in the Ming Jade was decreased from 19.2 ppm to 4.5 ppm. This corresponded to a 3-fold increase in suspended solids from 0.575 g/L to 1.505 g/L. The results …

Nucleation and growth of unsubstituted metal phthalocyanine films from solution on planar substrates
… to conventional solar cells. Unsubstituted Metal-phthalocyanines (Pc) are excellent electron donating molecules for heterojunction OSC. Usually organic solar cells with Pcs are produced by vapor deposition, although solution based deposition (like spin casting) is cheaper and offers more …

Organic/carbon nanotubes hybrid thin films for chemical detection.
Metallophthalocyanines (MPcs) are classified as an important class of conjugated materials and they possess several advantages attributed to their unique chemical structure. Carbon nanotubes (CNT), on the other hand, are known to enhance the properties of nano-composites in the conjugated …

Electronic properties of metal-organic and organic-organic interfaces studied by photoemission and photoabsorption spectroscopy
… heterointerfaces between fullerite and pristine copper phthalocyanine were studied. Both interfaces, CuPc/C60 and C60/CuPc, were found to be non-reactive with pronounced shifts of the vacuum level pointing to the formation of an interfacial dipole mainly at the CuPc side of the heterojunctions. …
