The present invention relates to a process for manufacturing stable and monodisperse biocompatible bismuth metallic (0) nanoparticles, in aqueous solution, using a water-soluble bismuth precursor, a water-soluble reducing agent and a coating agent. The process can be carried out in continuous flow. The invention also relates to corresponding stable biocompatible bismuth metallic (0) nanoparticles having hydrophilic, hydrophobic or fluorophilic properties and uses thereof, especially medical applications thereof such as theranostic applications.

crude product. Subsequent treatment with a branched alkylamine yields a columnar liquid-crystalline benzoperylene diimide whose mesophase is stable at room temperature despite its limited and non-centrosymmetric alkyl periphery. Its absorptionspectrum is markedly red-shifted compared to that of a similar benzoperylene triimide.
Atropoisomeric aromatic cores enhance disorder inside the supramolecular packing of disk‐shaped mesogens. Core‐extension of perylene with an atropoisomeric [4]helicene fragment thus gives rise to a room‐temperature liquid crystal even with extremely short sidechains. Replacement of diester moieties by imide substituents allows switching from donor‐ to acceptor‐type electronic characteristics.

hindered by the strongly deactivating effect of the first‐entering glyoxylic substituent, the double reaction is successful with the reactive arene perylene under long reaction times and with concomitant ester hydrolysis. The reaction is regiospecific, giving the 3,9‐regioisomer exclusively. This perylenylenediglyoxylic acid is condensed first with o‐bromophenylacetic acid and then with α‐branched alkylamines

rectangular mesophases have unusually elongated unit cells. The cisoid diimides with both alkylimide substituents on the same side of the oblong arene system show a much greater tendency to self‐assemble into fluid stacks of disks than their centrosymmetric isomers. With racemically branched alkyl substituents, uniform vertical surface alignment of the columns in the high‐temperature hexagonal mesophase
