A novel copolymer based on fluorene and perylene diimide with pendent amino groups (PF-PDIN), has been synthesized and developed as a cathode interlayer for inverted polymer solar cells (I-PSCs).

respectively. The solution photophysical behavior of the polymers was studied by UV–vis and photoluminescence spectroscopy as a function of PDI incorporation and cationic/zwitterionic functionality, resulting in the observation of tunable solution spectral features induced by core functionality and/or interzwitterion interactions. This new PDI-based polymer platform affords opportunities to modulate
Most known perylene diimides are lipophilic, with few exceptions of hydrophilic derivatives. Even in the latter case, the compounds have limited water solubility and show a strong tendency to self-aggregation. In this paper we present the synthesis of four new perylene derivatives with three and four basic side chains, obtained by functionalizing the bay-area of perylene. These molecules show great solubility in aqueous media as hydrochlorides and their tendency to self-aggregate is remarkably reduced with respect to the previously synthesized two-chained perylene diimides. Their different spectroscopic properties in various solvents and conditions are reported and discussed. (C) 2007 Elsevier Ltd. All rights reserved.
New highly hydrosoluble and not self-aggregated perylene derivatives with three and four polar side-chains as G-quadruplex telomere targeting agents and telomerase inhibitors
Four new perylene derivatives with three and four basic side-chains are reported here as G-cluadruplex interactive compounds. The new perylene derivatives are readily soluble in water and not self-aggregated, in contrast to what happens with the previously reported two side-chain perylene derivatives. All four compounds are able to induce the G-cluadruplex and to inhibit 50% of telomerase activity at about 5 mu M concentration, showing a similar efficiency with respect to each other. Molecular modelling studies are presented to try to explain these findings. (C) 2007 Elsevier Ltd. All rights reserved.

[EN] The coronene derivatives of general formula: (I); wherein R1, R2, R2', R3, R4 and R4', when present and different from H, represent hydrophilic chains, constitute a new family of compounds that can selectively induce the formation of G-quadruplex structures in the telomeric DNA, and can thus act as inhibitors of the telomerase enzyme, thereby inhibiting tumour proliferation. These compounds proved to have a strong anticancer activity in vitro, which was assessed with many human tumour cell lines. Preparations including the coronene derivatives of formula (I) as active ingredients are proposed as medicament for use in anticancer treatments. [FR] La présente invention concerne des dérivés du coronène de formule générale (I), dans laquelle R1, R2, R2', R3, R4 et R4', lorsqu'ils sont présents et différents de H, représentent des chaînes hydrophiles. Ces dérivés constituent une nouvelle famille de composés capables d'induire sélectivement la formation de structures G-quadruplexes dans l'ADN télomère, ce qui leur permet d'agir comme des inhibiteurs de la télomérase et ainsi d'inhiber la prolifération des tumeurs. Ces composés ont montré une forte activité anticancéreuse in vitro, d'après des évaluations réalisées sur de nombreuses lignées cellulaires tumorales humaines. L'invention concerne également des préparations contenant lesdits dérivés du coronène de formule (I) qui, en tant que principes actifs, sont utilisées comme médicaments dans des traitements anticancéreux.
