The dihydroisoindole strategy for the synthesis of linearly annelated π-extended porphyrins affords a common approach to tetrabenzo-, tetranaphtho-, and tetranthra porphyrins with variable functionality and substitution patterns, starting from a common type of precursors involving 4,7-dihydroisoindole moiety.

Over fifty years ago, Linstead and Elvidge described the syntheses of phthalocyanine- like macrocycles in which one or two of the interior metal-binding nitrogen atoms were replaced with aromatic C-H groups. We review here the coordination chemistry of these systems, with an emphasis on their unusual reactivity and the varying extent to which the C-H groups are activated by metal-binding.

A new synthesis of phthalonitriles, a method for the generation of dehydrophthalocyanines, phthalocyanine and naphthalocyanine-carbohydrate conjugates.

Reported here is what we believe is a new, potentially generalizable route to fully β-alkyl substituted calix[4]pyrroles. These products are accessible from the starting pyrrolic esters, and are obtained via reaction with CH₃Li, followed by subsequent quenching with HCl in ether. The present route allows access to calix[4]pyrroles bearing functionality, such as double bonds, off the so-called C-rim

Reversible supramolecular system based on sliding motion of coordination di mers of porphyrinatozinc-phthalocyaninatomagnesium heterodyad is described. Addition and removal of DMSO drive the motion on the basis of hard and soft acid and base principle. The sliding motion can be detected sensitively using UV-vis and fluorescence monitors.

Glucose-, galactose- and lactose-containing photosensitizers based on derivatives of chlorophyll a and acteriochlorophyll a were synthesized with the use of [3+2] cycloaddition between sugar azides and triple bond derivatives of chlorins and bacteriochlorins. bacteriochlorins. NMR studies allowed the elucidation of structure, tautomeric form and conformation of the obtained compounds.

Water soluble zwitterionic, as well as cationic and anionic triazatetrabenz-corroles, phthalocyanines and a porphyrin were prepared and investigated as sensitizers for the photooxidation of 2-mercaptoethanol. Compared to single-component sensitizers, a remarkable improvement of the photocatalytic activity by co-sen sitization using mixture of sensitizers was observed.

Azomethine ylides generated from the reaction of a corrole-3-carbaldehyde or a corrole-2-carbaldehyde and N-methylglycine were traped with dipolarophi les in 1,3-dipolar cycloadditions.

Two unsymmetrical Zn(II) phthalocyanines bearing an anchoring carbox carboxylic function linked to the phthalocyanine ring through different rigid arylenevinylene bridges have been designed for dye-sensitized solar cell (DSSC) applications. These phthalocyanines, when anchored onto nanocrystalline TiO₂ films, yielded 30% incident monochromatic photon-to-current conversion efficiency (IPCE) and 2% power conversion efficiencies under AM1.5 sun.

The effects of 9-substitution on the photophysical properties of tetraphenylpor-phycenes have been examined using an electron acceptor, an electron donor, and a bulky, electroneutral substituent as model compounds.

A new hydrophilic phthalocyanine containing antimony(V) as the central element bearing hydroxide has been synthesized via oxidative addition process and has been spectroscopically investigated.

Nucleophilic addition of 5-aryl substituted dipyrranes to acridine followed by the oxidation of adducts leads to 1-(acridin-9-yl)dipyrranes. These products were transformed into respective 1-(acridin-9-yl)dipyrrins via DDQ mediated oxidation. Spectroscopic studies led to the conclusion that there is a signifi cant conjugation between both moieties in molecules of 1-(acridin-9-yl)dipyrrins.
