A platinum(II) emitter is able to self‐assemble into gelatingnanofibers, leading to an unprecedented 90 % photoluminescence quantum yield. Electroluminescent devices processed in solution can be doped with the aforementioned complex. Picture: a) Emission (—) and excitation spectra (‐ ‐ ‐ ‐) and photos of the gel, b) REM, and c) TEM images of the nanofibers.
The invention relates to platinum complexes and their use in biomedical applications, like in vitro and in vivo imaging and cell staining. The present invention provides new materials and their use as imaging agent. The formation of luminescent aggregates can allow a switch of the emission leading to a dynamic label and on the formation of soft assemblies, which, in some cases, are even more emissive than the isolated corresponding species
