Diazocine (bridged azobenzene) can be switched in both directions upon selective excitation of two different coexisting triplet sensitizers. Compared to direct irradiation, switching wavelengths are strongly (≥130 nm) bathochromically shifted.

Polycystic ovarian disease in adolescents is not uncommon. Usually underlying ovarian tumours can cause hirsutism and ovulation. A 15-year-old girl presented with infrequent cycles and hirsutism. Her baseline evaluation ruled out ovarian tumour and other endocrinological problems. She was treated with insulin sensitizers and hormone treatment. After more than a year of treatment she developed a...

Six new heteroleptic Ru(II) complexes (MC118, MC120-123 and MC126), of general formula Ru(L1)(L2)(NCS)2, where L1 and L2 are respectively dicarboxylated and π-conjugated functionalized (dissymmetric) bipyridine ligands, were designed, synthesized and applied as sensitizers in dye-sensitized solar cells. These complexes were characterized both experimentally and theoretically, showing promising ...

Photodynamic therapy (PDT) is based on photosensitizers activated by light of appropriate wavelength. Their activation leads to generation of singlet oxygen and free radicals responsible for the cytotoxic effect. The aim of this project was to compare the bactericidal effect of PDT using different porphyrin photosensitizers against a methicillin-resistant Staphylococcus aureus strain. Exogenous...

Attempts have been made to develop dye-sensitized solar cells based on the principles and materials of photosynthesis: We first tested photosynthetic pigments, carotenoids (Cars), chlorophylls (Chls) and their derivatives, to find sensitizers showing reasonable performance (photocurrent and conversion efficiency). We then tried to introduce the principles of photosynthesis, including electron t...

Ultrafast recombination observed from several perylene imide sensitizers bound to NiO appears to align with Marcus normal region behaviour; this indicates recombination to intra-bandgap states.

The Bcl-2 family of proteins plays a critical role regulating apoptosis, and pro-survival Bcl-2 family members are important therapeutic targets due to their overexpression in different cancers. Pro-apoptotic Bcl-2 homology 3 (BH3)-only proteins antagonize pro-survival Bcl-2 protein functions by binding directly to them, and a sub-class of BH3-only proteins termed sensitizers can initiate apopt...

Indacenodithiophene-core-based D–π–A-type organic sensitizers with two different donor antennas (triphenylamine and phenothiazine) were designed synthesized for use as light-harvesting materials in dye-sensitized solar cell (DSSC) applications.

2,4-Dichlorobenzoic acid and a suite of models of chlorinated biphenyl carboxylic acids were found to be efficient sensitizers of the reactive oxygen species singlet oxygen (1O2).
