Abstract: The syntheses and spectroscopic properties of a series of pegylated zinc(II)-phthalocyanines (Zn-Pcs) containing one, two, or eight tri(ethylene glycol) chains are described. The single molecular structure of a phthalonitrile precursor containing one hydroxyl and one PEG group, and its unique intermolecular hydrogen bonding are presented. The pegylated Pcs are highly soluble in polar organic solvents and have fluorescence quantum yields in the range 0.08–0.28. [Copyright &y& Elsevier]

Abstract: In the presence of excess dimethylacetylene dicarboxylate (DMAD), nickel(II) pyrrolo[3,4-b]porphyrins undergo both Diels–Alder cycloaddition and Michael addition in toluene to give two bis-adducts, identified as compounds 4 and 5 ; the reaction can be accelerated by the addition of Lewis or Brønsted–Lowry acids. Refluxing the reaction mixture in 1,2,4-trichlorobenzene (220°C) leads to a nickel(II) monobenzoporphyrin 2 as the main product. The structure of compound 4 was confirmed by X-ray crystallography.

Abstract: The syntheses of two new A3B-type Zn(II)-phthalocyanines (Zn-Pcs) containing either one or two cobaltacarborane residues are reported, and the X-ray structure of a key phthalonitrile precursor is presented. The Zn-Pcs are highly soluble and exist as monomers in polar organic solvents. [Copyright &y& Elsevier]

A series of 14 symmetric ( 1a – g ) and asymmetric ( 2a – g ) BODIPYs bearing two different substituents at the boron center were synthesized in a one-pot reaction from dipyrrins 1 and 2 , respectively, in 14–63% isolated yields. The reaction involves the treatment of dipyrrin with phenylboron dichloride followed by nucleophilic substitution of the chloride group using various nucleophiles, including TBAF, TMSCN, ROH, acetate, and alkoxides. The reactions are completed within 2 h at room temperature. The spectroscopic and 11 B NMR properties of the new BODIPYs were investigated and three crystal structures are presented.

Abstract: The first syntheses of closo-carboranylcorroles ( 3 , 4 , and 11 ) have been achieved in a one-pot procedure from the condensation of pyrrole and carboranylbenzaldehydes, without the concomitant formation of the corresponding tetraarylporphyrins. The water-soluble nido-carboranylcorrole 9 was prepared from 7 in quantitative yield using tetrabutylammonium fluoride. The first X-ray molecular structure of a Cu(III) carboranylcorrole complex 7 is also presented. Carboranylcorroles absorb in the red region of the optical spectrum and should have potential application in both BNCT and PDT. [Copyright &y& Elsevier]
