The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Synthesis, characterization and photovoltaic behaviours of peripheral and non-peripheral tetra-[4-(4-octylpiperazin-1-yl)phenoxy] substituted zinc(II), cobalt(II), copper(II) and indium(III) phthalocyanines》. Authors are Artuc, Gamze Ozgul; Altindal, Ahmet; Eran, Belkiz Bilgin; Bulut, Mustafa.The article about the compound:4-(Piperazin-1-yl)phenolcas:56621-48-8,SMILESS:OC1=CC=C(N2CCNCC2)C=C1).Electric Literature of C10H14N2O. Through the article, more information about this compound (cas:56621-48-8) is conveyed.
The synthesis of zinc(II), cobalt(II), copper(II) and indium(III)(OAc) phthalocyanines carrying four 4-(4-octylpiperazin-1-yl)phenoxy moieties in peripheral/non-peripheral positions were performed by the cyclotetramerization of compounds 4-[4-(4-octylpiperazin-1-yl)phenoxy]phthalonitrile or 3-[4-(4-octylpiperazin-1-yl)phenoxy]phthalonitrile with resp. metal salts. The novel phthalonitriles and phthalocyanines were characterized by elemental and spectroscopic anal., including 1H NMR, 13C NMR, FTIR, UV-visible spectral and MALDI-TOF mass data. To clarify the influence of the position of substituent group and the variety of the central metal atom on the photovoltaic performance, bulk heterojunction devices by using phthalocyanines with different blend ratio, as donor was fabricated and characterized.
I hope my short article helps more people learn about this compound(4-(Piperazin-1-yl)phenol)Electric Literature of C10H14N2O. Apart from the compound(56621-48-8), you can read my other articles to know other related compounds.
