was further evidenced by caspase activation and mitochondrial membrane potential (MMP) biomarkers and was complemented by brain histology and electron microscopy data which revealed that the PFBZ chaperone provided a protective coating over the amyloid surface and resists from interacting with cell membrane and prevents inducing toxicity. This conjugated polymer artificial chaperone-based nanodrug showed

the alkylation of fluorene achieved via direct C−H alkylation under aqueous conditions is reported, wherein the formation of fluorenone is inhibited, resulting in the exclusive formation of the desired dialkyl-substituted fluorene monomer. As a proof of concept, this method has also been successfully extended to perform N-alkylation of carbazole, diphenylamine, and N,N-dialkylation of aniline in high

five fluorene-based gold(I) complexes are synthesized and characterized. They exhibit typical aggregation-induced emission (AIE) properties or significant aggregate fluorescence change behaviors. Their thin-film and solid state fluorescence spectra are consistent with the luminescence of all luminogens in DMF–H2O mixtures with high water content. The emission color changes with different numbers of

A pre-targeted anchor strategy was developed to regulate the intracellular distribution of bioactive molecules in specific organelles based on bioorthogonal tetrazine ligation.
The invention relates to a resin composition which comprises a polymer having a divalent oligofluorene as a repeating unit therein, wherein the divalent oligofluorene contains at least two fluorene units optionally having a substituent, and the 9-positioned carbon atoms of the fluorene units bond to each other via a direct bond or via an alkylene group optionally having a substituent, an arylene group optionally having a substituent, or an aralkylene group optionally having a substituent, and a ratio of a retardation measured at a wavelength of 450 nm (Re450) to a retardation measured at a wavelength of 550 nm (Re550) satisfies the following formula (2): Re450/Re550≦1.0.
