Retracted article: Hydrophilic hybrid materials with magnetism & NIR fluorescence via surface-initiated RAFT polymerization

Abstract

We, the named authors, hereby wholly retract this Journal of Materials Chemistry B article due to the subsequent realisation that fluorescence measurements reported in the article should have been measured through a long-pass filter. The emission at 750 nm reported from the excitation of the monomer 1-(4-vinyl benzyl)-2-naphthyl-benzimidazole by UV light, is actually a second order diffraction artefact of the 380 nm emission. The claim that the monomer is capable of emitting near infrared fluorescence under UV light excitation in the article is false.
