  Synthesis, characteristics and photochemical studies of novel porphyrazines possessing peripheral 2,5-dimethylpyrrol-1-yl and dimethylamino groups

  摘要：

  The synthesis and physicochemical properties of novel porphyrazines possessing an alternate system of two peripheral substituents, 2,5-dimethylpyrrol-1-yl and dimethylamino, are presented. All the macrocycles were subjected to HPLC purity studies. Spectroscopic studies of magnesium(II) porphyrazine encompassed steady state absorption, emission measurements, including fluorescence decays, transient absorption spectra, and thermoluminescence. Additionally, magnesium(II) porphyrazine was found to be a moderate photosensitizer with singlet oxygen generation values of 0.12 and 0.14 in DMF and DMSO, respectively. Comparison of the quantum yields of singlet oxygen generation before and after deoxygenation showed that the photodynamic effect of magnesium(II) porphyrazine is governed by the photosensitization mechanism II. Magnesium(II) and manganese(III) porphyrazines were characterized using X-ray crystallography. (C) 2012 Elsevier Ltd. All rights reserved.

  Microwave-assisted organic synthesis approaches were used in the Paal-Knorr reaction leading to the modified diaminomaleonitrile intermediates and the Suzuki-Miyaura reaction, which allowed the obtaining of porphyrazine derivative. All compounds were characterized using UV–Vis, 1H and 13C NMR, including 2D techniques, as well as MS (ES or MALDI). An X-ray analysis of magnesium(II) porphyrazine with peripheral

  For the synthesis of precursors to cellulose-based ion exchange materials, the condensation of diaminomaleonitrile with 2,4-pentanedione and 2,5-hexanedione was explored. Whilst the former diketone yielded the expected l,4-diazepine (2), the latter gave either a pyrrole derivative (3) or an unusual triazabicyclononene (4), depending on the conditions lsed. Compound 4 crystallizes in the monoclinic space group P2(1)/c with a = 8.9313(10) Angstrom, b = 9.0370(7) Angstrom, c = 11.4448(9)Angstrom. beta = 102.48(8)degrees, V = 901.89(14) Angstrom (3), and Z = 4. Compound 3 crystallizes in the orthorhombic space group Pna2(1) with a = 12.0342(8) Angstrom, b = 8.3760(8) Angstrom, c = 10.7026(11) Angstrom, V = 1078.81(17) Angstrom (3), and Z = 4. Compound 4 crystallizes in the monoclinic space group P2(1)/c with a = 9.0157(5) Angstrom, b = 13.5374(9) Angstrom, c = 12.8751(16) Angstrom, beta = 99.506(5)degrees, V = 1549.82(15) Angstrom (3), and Z = 4. In both 3 and 4 the aminovinyl substituent shows evidence for involvement of the lone pair on nitrogen with the carbon pi -system. Also, 3 and 4 are highly associated in the solid state via hydrogen bonding.
