Get this from a library. The production of copper phthalocyanine and/or its derivatives. [Tomio Segawa; United States. National Aeronautics and Space Administration.;]. Phthalocyanine is of course closely related to the highly coloured porphyrins which are classed as polyene chromogens, and contain no donor or acceptor groups.
The very important blue pigment copper phthalocyanine is a tetraazatetrabenzoporphin and the basic polyene chromogen of the molecule is as in (), which has an aza-annulene type colour of the molecule is. Copper phthalocyanine derivatives of the formula ##STR1## or mixtures thereof wherein CuPc is optionally substituted copper phthalocyanine, n is a value from 1 to 4, X is hydrogen, C alkyl, C alkoxy or halogen, and R is linear or branched alkyl of 1 to 22 C-atoms which may be substituted with one or more alkoxy, dialkylamino or alkylthio, the alkyls having 1 to 22 C Cited by: 5.
During the last decade, due to the chemical and thermal stability (Sayyad, ), phthalocyanine (Pc) and its metal derivatives (MPcs) have acquired great attention for their potential use in. b-Copper Phthalocyanine Blue is one of the tinctorially strong pigments, although its strength is approximately 15 to 20% below that of a-Copper Phthalocyanine Blue.
At standard conditions, 1/1 SD letterpress proof prints are formulated at 16% of a tinctorially strong type of P.B, but require approximately 21% b -Copper Phthalocyanine Blue. Page Phthalocyanine sulfoacids and their derivatives Phthalocyanine sulfoacids and their derivatives - alkali metal salts, sulfoacid esters, sulfamides, and sulfones - are an important class of substituted phthalocyanine compounds, mostly used as textile and printing dyes and more recently, in photodynamic therapy of cancer and Cited by: The quantum yield of the singlet oxygen production was determined for eight phthalocyanine derivatives; the following sequence was obtained: 5 ∼ 4 >.
In this work, thin films of vanadyl phthalocyanines (VOPc and VOPcF4) are studied as active layers for the detection of gaseous ammonia and hydrogen. The effect of F-substituents on the structural features of vanadyl phthalocyanine films and their sensor response toward ammonia (10–50 ppm) and hydrogen (– ppm) is investigated by X-ray diffraction (XRD) and.
The author of the review described photosensitizers based on phthalocyanines and naphthalocyanines for photodynamic therapy of cancer, used template synthesis for CuPcs and AlPcs. 2,9,16,Tetra(4-carboxyphenoxy)phthalocyanine zinc(II) and its derivatives for efficient near-IR sensitization of nanocrystalline TiO 2 films were produced by the Author: Tatyana N.
