“…In this sense, investigating the changes in the semiconductor behavior of the Pc in the presence of different metals and substituents is of fundamental importance to evaluate the suitability of the resulting system, in terms of applications [13,14]. One of the most studied MPcs is copper phthalocyanine (CuPc) due to its large ring binders closely related to porphyrins, and because constitutes an important class of tissue dyes [15]. Its strong absorption in the Q band (600-800 nm) and its excellent photoinduced charge generation efficiency ease its application in xerographic photoreceptors of laser printers [16].…”

We report the structural organization and its effect on the current response of the conducting domains in MPcs (M = Cu, Co, Zn) films, deposited by vacuum thermal evaporation and doped by the presence of iodine vapors. Structural and surface features of the doped metallophthalocyanines (MPcs) were studied by using IR spectroscopy, X-ray diffraction, atomic force microscope (AFM) and scanning electron microscope (SEM). DFT calculations were carried to study the interaction between iodine and MPcs molecules and establish the influence of iodine on the electronic behavior of these species and the changes on the frontier molecular orbitals. This interaction is thermodynamically favored, and the mechanism of electronic transit involving the iodine atoms providing electrons to the transfer. The I-MPc films have a mainly amorphous structure, some crystallinity in the MPcs α and β forms. A roughness between 18.41 and 99.02 nm and particle size between 1.35 and 15 μm. By evaluating the electrical behavior of the flexible PET/ITO/I-MPc/Ag devices, it was found that J-V curves under illuminated conditions show an increase of curves values upon the I-MPc, indicating that the flexible films are photosensible. Jsc between 1.59 × 10−5 and 2.41 × 10−7 A/cm2, conductivities between 6.17 × 10−8–2.54 × 10−7 Scm−1 and photosensibility values of up to 133%.

In this work, we report the synthesis of novel inorganic-organic hybrid nanomaterials (GO@Fe 3 O 4 /CuPc) and GO@Fe 3 O 4 /ZnPc) consisting of sheets of graphene oxide (GO) decorated by iron oxide nanoparticles (Fe 3 O 4 ), the whole heterostructure functionalized with metallo-phthalocyanines (MPc, M:Cu or Zn). First the synthesis of nanomaterial (GO@Fe 3 O 4 ) was prepared by hydrothermal self-assembly process through the mixture of graphene oxide and Fe ?2 /Fe ?3 salt solution. The metallo-phthalocyanines anchorage on the surface of nanosystem was lately performed by facile and effective ultrasonication method. The structure, composition and morphology of nanohybrids and intermediates were investigated by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, UV-visible spectroscopy, scanning and transmission electron microscopy and impedance spectroscopy. All the results suggested that iron-based nanoparticles were successfully deposited onto graphene oxide sheet networks in the form of Fe 3 O 4 , forming nanospheres, decreasing in lattice defects of the GO sheets and dramatically increasing the dielectric properties of nanosystems. Nanomaterials presented saturation magnetization in the 52-58 emu/g and superparamagnetic

“…The target p‐type molecule was designed and obtained by employing CuPC as the core structure due to its outstanding photosensitivity and high‐carrier mobility. [ 20,21 ] To expand the absorption range, eight 4‐ethynyl‐ N,N ‐bis(4‐methoxyphenyl)aniline groups are grafted into the peripheral side chains of CuPC to obtain 8TPAEPC with good thermal stability ( Figure a; Figure S1, Supporting Information). Meanwhile, ethynyl groups are used as π‐bridges to connect the triphenylamine groups and CuPC.…”

The absent photo‐response in near‐infrared (NIR) light (>800 nm) of lead‐based perovskite solar cells (PSCs) limits the further improvement of their power conversion efficiency (PCE). Here, a narrow bandgap p‐type phthalocyanine derivative (Copper(II) 2,3,9,10,16,17,23,24‐octakis((4‐(bis(4‐methoxyphenyl)amino)phenyl)ethynyl)phthalocyanine –8TPAEPC) with NIR absorption is synthesized to extend the photovoltaic response of perovskite to 850 nm. After doping the 8TPAEPC into the perovskite photoactive layer, the perovskite crystal quality is improved, resulting in its good electrical conductivity and less surface defects. Furthermore, the molecules stacking on the grain boundaries construct the charge transportation paths, as well as the p–n bulk heterojunction with enhanced built‐in potential. The target PSCs are optimized with notably enhanced PCE from 20% up to 22.10%, and excellent stability that is over 80% of the initial level at 70–80% relative humidity can be maintained for more than 500 h, benefiting from the improved hydrophobicity of 8TPAEPC. In addition, 8TPAEPC also serves as a dopant‐free, highly carrier‐mobile, and moreover, NIR‐responsive hole transport layer (HTL) with boosted PCE of 20.42% that reaches state of the art level among the dopant‐free metal phthalocyanines HTL‐based PSCs.
