Tetraphenylethene End-capped Polyethylenimine Fluorescent Nanoparticles for Cell Imaging

Water soluble tetraphenylethene-based（TPE） aggregation-induced emission fluorescent organic nanoparticles（FONs） were facilely prepared via Schiff base condensation with polyethylenimine（PEI） and subsequent reduction. The obtained TPE-PEI FONs were characterized by a series of techniques including 1H...

Description
Summary:Water soluble tetraphenylethene-based（TPE） aggregation-induced emission fluorescent organic nanoparticles（FONs） were facilely prepared via Schiff base condensation with polyethylenimine（PEI） and subsequent reduction. The obtained TPE-PEI FONs were characterized by a series of techniques including 1H-NMR, 13C-NMR, gel permeation chromatography, UV absorption spectra, fluorescence spectra, Fourier transform infrared spectroscopy, size distribution and zeta potential measurement, and transmission electron microscopy. Biocompatibility evaluation and cell imaging of TPE-PEI FONs were further explored. We demonstrated that such FONs showed intense fluorescence, spherical morphology and excellent biocompatibility, making them very suitable for cell imaging application.
