A water-soluble perylene dye functionalised with a 17β-estradiol: a new fluorescent tool for steroid hormones.

We have successfully been able to synthesise a specific estrogen receptor-directed biolabel based on a fluorescent water-soluble perylenebisimide, thus offering great potential for determining the presence of estrogen receptors in any kind of cell. Moreover, this synthetic strategy allows the preparation of other conjugates involved in the study of any kind of receptor, simply by selecting the appropriate agonist or antagonist.

Alkoxy-styryl DCDHF fluorophores.

A photostable dicyanomethylenedihydrofuran fluorophore which contains electron-donating alkoxy groups is described. This chromophore is highly environmentally-sensitive, which is a remarkable property for a fluorescent reporter. Its light excitation also enables, in low viscous solvents, the formation of dark states whose radical or triplet nature is ruled out.

Efficient deep-red light-emitting electrochemical cells based on a perylenediimide-iridium-complex dyad.

A two-layer light-emitting electrochemical cell device based on a new perylenediimide-iridium-complex dyad is presented emitting in the deep-red region with high external quantum efficiencies (3.27%).
