A Porphyrin-Involved Benzene-1,3,5-Tricarboxamide Dendrimer (Por-BTA) as a Multifunctional Interface Material for Efficient and Stable Perovskite Solar Cells

Yi Zhang, Bing Zhang, Peng Zhao

Surface defects of perovskite films are the major sources of nonradiative recombination which limit the efficiency and stability of perovskite solar cells. Surface passivation represents one of the most efficient strategies to solve this problem. Herein, f ...

Lewis acid catalyst-steered divergent synthesis of functionalized vicinal amino alcohols and pyrroles from tertiary enamides

Jieping Zhu, Shuo Tong

We report herein two Lewis acid catalyst-steered distinct reaction pathways of N-formylmethyl tertiary enamides. In the presence of a catalytic amount of AlCl3 and 4 angstrom molecular sieves, the stable N-formylmethyl tertiary enamides underwent sequentia ...

Synthetic Approaches to Functional Derivatives of Cycl[3.2.2]Azine-1,2-Dicarboxylic Acid - Perspective Building Blocks for pi-Extended Macrocyclic Compounds

Fedor Zhurkin

One of the actual goals in the field of macrocyclic research is to provide accessible chemically robust compounds with absorption in the NIR spectral region. This requirement can be fulfilled in the case of tetrapyrrolic derivatives such as porphyrins, pht ...

Salvage of the essential corrinoid cofactor in Dehalobacter restrictus

Christof Holliger, Julien Maillard, Yue Lu, Aamani Rupakula Boyanapalli, Sébastien Keller, Hauke Smidt

The corrinoid cofactor is essential for organohalide respiration (OHR), a bacterial metabolism assisting towards environmental depollution. Two different strategies for obtaining corrinoids, are used by OHR bacteria, either de novo biosynthesis or salvagin ...

Molecular Engineering of Push-Pull Porphyrin Dyes for Highly Efficient Dye-Sensitized Solar Cells: The Role of Benzene Spacers

Michael Graetzel, Shaik Mohammed Zakeeruddin, Aswani Yella, Chi-Lun Mai

Porphyrins have drawn much attention as sensitizers owing to the large absorption coefficients of their Soret and Q bands in the visible region. In a donor and acceptor zinc porphyrin we applied a new strategy of introducing 2,1,3-benzothiadiazole (BTD) as ...

Oxygen reduction catalyzed by a fluorinated tetraphenylporphyrin free base at liquid/liquid interfaces

Hubert Girault, Manuel Alejandro Méndez Agudelo, Bin Su, Imren Hatay, Zdenek Samec

The diprotonated form of a fluorinated free base porphyrin, namely 5-(p-aminophenyl)-10,15,20-tris(pentafluorophenyl)porphyrin (H(2)FAP), can catalyze the reduction of oxygen by a weak electron donor, namely ferrocene (Fc). At a water/1,2-dichloroethane in ...

Highly Efficient Mesoscopic Dye-Sensitized Solar Cells Based on Donor-Acceptor-Substituted Porphyrins

Michael Graetzel, Shaik Mohammed Zakeeruddin, Takeru Bessho

To dye for: A porphyrin chromophore, which is integrated into a donor-acceptor dye as a π-conjugated bridge (see picture), exhibits an unprecedented efficiency of 11 □ % when used as a photosensitizer in a double-layer TiO2 film. A greatly enhanced photovo ...

Assessment of a sheep animal model to optimize photodynamic therapy with Foscan in the esophague

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, François André Borle

Precursor lesions of oesophagus adenocarcinoma constitute a clinical dilemma. Photodynamic therapy (PDT) is an effective treatment for this indication, but it is difficult to optimise without an appropriate animal model. For this reason, we assessed the sh ...

Photodynamic therapy for 101 early cancers of the upper aerodigestive tract, the esophagus, and the bronchi: a single-institution experience

Hubert van den Bergh, Georges Wagnières, Alain Woodtli

Cancer, when detected at an early stage, has a very good probability of being eradicated by surgery or radiotherapy. However, less aggressive treatments also tend to provide high rates of cure without the side effects of radical therapy. We report on the r ...
