“…19,20-Dicyano substituted macrocycle which synthesized by treating the dibromo compound 5 with three equivalents of CuCN according to Rosenmund von Braun reaction [30] in a moderately high-boiling solvent such as DMF at 150°C under nitrogen atmosphere. After this reaction, the desired compound 6 was purified by column chromatography on silica gel using chloroform as eluent, was completed in 76% yield.…”

“…2). The IR spectrum of 5 clearly indicates the disappearance of the C=N groups after the conversion of 4 to metal-free phthalocyanine 5, which shows a new absorption at 3298 cm À1 for the N-H groups [24,25]. The mass spectrum of 5 was obtained by the fast atom bombardment technique.…”

New metal-free 5 and metallophthalocyanines 6-11 (M = Cu, Ni, Co, Pb, Zn) fused in peripheral positions with four 24-membered tetraoxatetraaza macrocycles were prepared by cyclotetramerization of 24,25-dicyano-4,10,13,17-tetra(toluene-p-sulfonyl)-1,2, 3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22-didicontinehydrobenzo[y][3,9,12,18]tetraaza [1,7,16,22]tetraoxatetradicontine in the presence of the corresponding metal salt or a strong organic base. While the N-tosylated derivatives of the phthalocyanines are soluble in common organic solvents, the detosylated derivative of copper phthalocyaninate is soluble in water. The aggregation properties of the phthalocyanines were also investigated as a function of concentration, solvent and oxidative medium. The new compounds are characterized by a combination of elemental analysis and 1 H NMR, 13 C NMR, IR, UV-vis and MS specral data.

“…[29][30][31] In addition, a characteristic absorption band at 2230 cm -1 belonging to the symmetric stretching vibration of nitrile groups (-CN) was clearly observed in HBCuPc@CNTs-Fe 3 O 4 particles, which demonstrated that the HBCuPc has been coated onto the CNTs-Fe 3 O 4 surface. The results were in accordance with the previous work.…”

Core-shell structured magnetic carbon nanotubes (CNTs-Fe 3 O 4 ) coated with hyperbranched copper phthalocyanine (HBCuPc) (HBCuPc@CNTs-Fe 3 O 4 ) hybrids were prepared by the solvent-thermal method. The results indicated that the HBCuPc molecules were decorated on the surface of CNTs-Fe 3 O 4 through coordination behavior of phthalocyanines, and the CNTs-Fe 3 O 4 core was completely coaxial wrapped by a functional intermediate HBCuPc shell. Then, polymer-based composites with a relatively high dielectric constant and low dielectric loss were fabricated by using core-shell structured HBCuPc@CNTs-Fe 3 O 4 hybrids as fillers and polyarylene ether nitriles (PEN) as the polymer matrix. The cross-sectional scanning electron microscopy (SEM) images of composites showed that there is almost no agglomeration and internal delamination. In addition, the rheological analysis reveals that the core-shell structured HBCuPc@CNTs-Fe 3 O 4 hybrids present better dispersion and stronger interface adhesion with the PEN matrix than CNTs-Fe 3 O 4 , thus resulting in significant improvement of the mechanical, thermal and dielectric properties of polymer-based composites.
