Photoinduced electron transfer in supramolecular assemblies involving saddle-distorted porphyrins and phthalocyanines
Takahiko Kojima, Tatsuaki Nakanishi, Tatsuhiko Honda and Shunichi Fukuzumi
DOI No: 10.1142/S1088424609000164
Page: 14-21
Saddle-distorted dodecaphenylporphyrin (H2DPP) can undergo facile protonation to give a stable diprotonated species, H4DPP2+. H4DPP2+ can be a building block to construct novel supramolecular assemblies with hydroquinone derivatives for "porphyrin nanochannels" and with saddle-distorted Zn(II)-phthalocyanine complexes. In those supramo lecules, H4DPP2+ acts as an electron acceptor in the photoinduced electron transfer.

DOI No: 10.1142/S1088424609000061
Page: 22-34
In this review, recent research on porphyrin assemblies, including two-dimensional porphyrin arrays, is described with emphasis on phenol- and quinone- substituted tetrapyrrole units. A series of research aimed at developing strategies for preparation of porphyrin molecular arrays, where several novel aspects of molecular arrays, including phase transitions, ordered 2-D phase boundaries, and hydrogen-bonding networks, are introduced.

Interaction of nitric oxide with Ru(II) complexes of deuteroporphyrindimethylester derivatives
Rudy Martin, Roberto Paolesse Cao, Ana M. Esteva and Franz-Peter Montforts Montforts
DOI No: 10.1142/S1088424609000188
Page: 35-40
The structure and physical properties of a series of N-substituted hemiquinone-substituted oxoporphyrinogens is presented and discussed. Structures, electrochemical properties and use of the compounds as supramolecular tectons are described. Also presented are properties related to guest binding and photophysical properties of oligo-chromophoric host-guest complexes involving oxoporphyrinogen N-substituted with porphyrins and appropriately substituted fullerene guest electron acceptors.

Synthesis of porphyrin-carbohydrate conjugates using "click" chemistry and their preliminary evaluation in human HEp2 cells
Erhong Hao, Timothy J. Jensen and M. Graça H. Vicente
DOI No: 10.1142/S1088424609000085
Page: 51-59
We describe the syntheses of a series of four new porphyrin-carbohydrate conjugates containing either one or four galactose or lactose moieties linked via triazole units to a meso-phenyl group of a TPP or TBP macrocycle. The most efficiently accumulated within human carcinoma HEp2 cells of all the conjugates was the TBP-galactose, localizing preferentially in the lysosomes. The TPP-galactose and -lactose conjugates were found mainly in the cell ER and endosomes.

Daniel Filippini, Emanuela Gatto, Adriano Alimelli, Muhamad Ali Malik, Corrado Di Natale, Roberto Paolesse, Arnaldo D'Amico and Ingemar Lundström
DOI No: 10.1142/S1088424609000152

Recent progress in spectral fingerprinting of fluorescent indicators using distributed instrumentation based on consumer electronic devices is reviewed. In particular, the evaluation of disposable assays using a computer screen photo-assisted technique (CSPT) is discussed. Sample identification and optimization strategies are analyzed as well as the underlying theoretical background for polychromatic spectral fingerprinting.

The supramolecular wires over 600 nm in length based on ruthenium(II) tetra- 15-crown-5-phthalocyaninate with triethylenediamine molecules have been observed by use of atomic force microscopy. The third order nonlinear optical characteristics of complexes in tetrachloroethane solution were studied by z-scanning method. Molecular polarizability of the complex is about 4.5 x 10-32 esu and increases by factor of 3.6 when the individual molecule assembles into a supramolecular aggregate.

Martin Bröring, Markus Funk and Carsten Milsmann
DOI No: 10.1142/S1088424609000139
Page: 107-113
Several pathways and strategies have been thought and evaluated for the preparation of superstructured and chiral corrole ligands. Palladium catalyzed amidations of o-bromophenyl substituents at the stage of the completed corrole macrocycle is the key to a successful synthesis of such sterically encumbered ligands.

DOI No: 10.1142/S108842460900022X
Page: 122-135
Bicyclo[2.2.2]octadiene (BCOD)-fused porphyrins with no other substituents were prepared by the [2+2] and [3+1] porphyrin syntheses from ethanodihydroisoindole derivatives in fairly good yields. Thermal retro-Diels-Alder reactions of BCOD-fused porphyrins gave the corresponding benzoporphyrins with no substituent in quantitative yields.

Page: 136-152
Chloroiron(III) tetraphenylporphyrin, Fe(TPP)Cl, is an active catalyst for the cycloaddition of carbenes obtained from para-substituted methyl 2-phenyldiazoacetates to arenes to form rapidly equilibrating mixtures of norcaradienecycloheptatriene valence isomers in yields over 70%. This one-pot process is used with benzene, chlorobenzene, anisole, p-xylene, p-chlorotoluene (etc.) as substrates.

DOI No: 10.1142/S1088424609000048
Page: 153-160
Metallophthalocyanines (MPcs), including MPc analogues such as tetrabenzotriazaporphyrin (TBTAPs) and triazatetrabenzcorroles (TBCs) are effective as photosensitizers depending on the nature of the central metal and axial ligands. The synthesis and photophysics of phosphorous Pc, TBTAP and TBC complexes is reported.

A first ABAC phthalocyanine
Fabienne Dumoulin, Yunus Zorlu, M. Menaf Ayhan, Catherine Hirel, Ümit Isci and Vefa Ahsen
DOI No: 10.1142/S1088424609000140
Page: 161-165
The derouting of the selective synthesis of crosswise phthalocyanines (Pcs) ap plied to a statistical precursors mixture leads to a first member of a new family of Pcs bearing three different substituents: the ABAC phthalocyanines. By playing on precursors' relative ratio, yields and selectivity of the method have been optimized.
