One of the mysteries of the English language finally explained.
1A greenish-blue crystalline dye of the porphyrin group.
- ‘Organic compounds such as phthalocyanine produce greens and blues.’
- ‘As discussed previously, the phthalocyanine interacts with either the phospholipids or the apoprotein moiety of LDL, and therefore, the radicals are likely to be mainly produced at the lipid-water interface.’
- ‘In general, these newer drugs have been based on the structure of chlorin, purpurin, phthalocyanine or naphthalocyanine.’
- ‘By attaching differing substituent groups, some of which are water soluble and some of which are fat soluble, an unsymmetrically substituted phthalocyanine is created which is both water and fat soluble.’
- ‘This spectrum clearly indicates efficient singlet-singlet energy transfer from carotenoid to phthalocyanine.’
- 1.1 Any of a large class of green or blue pigments and dyes that are chelate complexes of this compound or one of its derivatives with a metal (in particular, copper).
- ‘It was found that a combination of cobalt or iron phthalocyanine and sodium ascorbate has high in vitro and in vivo antitumor activity.’
- ‘Previous investigators have demonstrated that sulfonated aluminum phthalocyanine is primarily distributed outside the nucleus.’
- ‘The suppression of the photodynamic potency of aluminum phthalocyanines was attributed to desorption of the dyes from lipid bilayers induced by fluoride or hydroxyl ions.’
- ‘Among the aluminum phthalocyanines, the hydrophilic tetrasulfonated derivative is localized in the vascular stroma and induces tumor regression by the indirect mechanism of vascular destruction.’
1930s: from phthalic (see phthalic acid) + Greek kuan(e)os ‘dark blue’ + -ine.
