Considerable efforts have been made in recent years to identify an optimal treatment method for the removal of antibiotics from wastewaters. A series supramolecular organic-inorganic magnetic composites containing Zn-modified MgAl LDHs and Cu-phthalocyanine as photosensitizers were prepared with aim removing β-lactam aqueous solutions. The characterization these materials confirmed anchorage on...

This work reports the non-covalent functionalization of SWNTs with Fe-porphyrin, Co-porphyrin and Co-phthalocyanine molecules. The functionalized were first characterized using Raman X-ray photoelectron spectroscopies. Observations down to nanoscale resolution also performed by atomic force microscopy, as well scanning transmission electron microscopies. spectroscopic methods evidenced an elect...

The effects of seven macrocyclic compounds comprising four phthalocyanines (Pcs) namely 1,4,8,11,15,18,22,25-octabutoxy-29H,31H-phthalocyanine (Pc1), 2,3,9,10,16,17,23,24-octakis(octyloxy)-29H,31H-phthalocyanine (Pc2), 2,9,16,23-tetra-tert-butyl-29H,31H-phthalocyanine (Pc3) and 29H,31H-phthalocyanine (Pc4), and three naphthalocyanines namely 5,9,14,18,23,27,32,36-octabutoxy-2,3-naphthalocyanine...

<p>The sensitivity of a QCM-based VOCs sensor with two kinds metal phthalocyanine, i.e., copper phthalocyanine (CuPc) and zinc (ZnPc) was examined for various VOCs. The the determined by compatibility overlapped orbitals (Cu(II) dan Zn(II)) corresponding CuPc ZnPc layer were deposited on quartz crystal oscillator vacuum evaporation method. frequency shift sensors functional layers tested ...

The intermolecular interaction among phthalocyanine molecules deposited on Ag(111) has been investigated at submonolayer coverages. By means of infrared absorption spectroscopy and spot-profile analysis low-energy electron diffraction, unambiguous evidence for an attractive between neighboring titanyl-phthalocyanine (TiOPc) is found dilute layers, which in contrast to the repulsion reported cop...

Noncovalent interactions, of which London dispersion is an important special case, are essential to many fields of chemistry. However, treatment of London dispersion is inherently outside the reach of (semi)local approximations to the exchange-correlation functional as well as of conventional hybrid density functionals based on semilocal correlation. Here, we offer an approach that provides a t...

A simple one-pot solution-processed OFET memory device has been fabricated based on the vertical phase separation of phthalocyanine-cored star-shaped polystyrene and an organic semiconductor.

A multimodular donor-acceptor tetrad featuring a bis(zinc porphyrin)-(zinc phthalocyanine) ((ZnP-ZnP)-ZnPc) triad and bis-pyridine-functionalized fullerene was assembled by a "two-point" binding strategy, and investigated as a charge-separating photosynthetic antenna-reaction center mimic. The spectral and computational studies suggested that the mode of binding of the bis-pyridine-functionaliz...
