We have designed and synthesized amphiphilic environment-sensitive fluorophore, POLARIC™, from four building blocks using Suzuki–Miyaura cross-coupling. The absorption and fluorescence spectra were measured in various micelles and vesicles. The results show that the emission wavelengths of these probes respond to the surface charge and stability of the self-assemblies.

The present invention relates to novel chemical compounds formula (I) (C)n-B-(A)m-B-(C)n (I) wherein m is 0 or 1, and n is independently 0, 1, 2 or 3, A, each B and each C are independently selected from phenylene and five-and six-membered heteroaromatic rings, and for a terminal ring B or C also from bicyclic heteroaromatic fused rings having seven to ten ring members, wherein the bond between at least two of the rings A to C may be replaced by a carbonyl group (-CO-), wherein at least two of the rings A to C are substituted with one or two groups R, and wherein each ring A to C further optionally is substituted with one or two groups R1. The compounds are useful in therapy, especially therapy of a mammal suffering from a disease involving misfolded or aggregated forms of proteins.

The present invention relates to novel labelled compounds of formula (I) (C)n-B-(A)m-B-(C)n (I) wherein m is 0 or 1, and n is independently 0, 1, 2 or 3, A, each B and each C are independently selected from phenylene and five- and six-membered heteroaromatic rings, and for a terminal ring B or C also from bicyclic heteroaromatic fused rings having seven to ten ring members, wherein the bond between at least two of the rings A to C may be replaced by a carbonyl group ( -CO- ), wherein at least two of the rings A to C are substituted with one or two groups R, and wherein each ring A to C further optionally is substituted with one or two groups R1, for use in imaging amyloid deposits and aggregated protein in living patients. The invention further relates to imaging methods using labelled or unlabelled compounds of formual I and the use of unlabelled compounds in such methods.

synthesis of two types of bis-8-hydroxyquinolines, prepared via either an imination or a Suzuki-Miyauracoupling approach, as well as their analysis is discussed. Imination was pursued through the condensation of quinolinecarbaldehydes with diamines or aminoquinolines with dialdehydes, and the Suzuki-Miyauracoupling reactions were evaluated using a bromoquinoline substrate and diboronic acids.

study explores a new mode of contortion in perylenediimides where the molecule is bent, like a bow, along its long axis. These bowed PDIs were synthesized through a facile fourfold Suzuki macrocyclization with aromatic linkers and a tetraborylated perylenediimide that introduces strain and results in a bowed structure. By altering the strings of the bow, the degree of bending can be controlled from
