Hyperbranched polyester nanorods with pyrrolo[2,1-a]isoquinoline end groups for fluorescent recognition of Fe3+

Abstract

Herein, we reported the synthesis of hyperbranched aromatic–aliphatic co-polyester nanorods HBPE-CICA6 and HBPE-CICA2 by modifying the periphery of second generation hyperbranched polyester (HBPE) with 1-cyano-pyrrolo[2,1-a]isoquinoline-3-carboxylic acid (CICA) groups. Structures of the HBPE-CICAs were confirmed by combined studies of Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (1H NMR), transmission electron microscopy (TEM), atomic force microscopy (AFM) and X-ray diffraction (XRD). The potential application of HBPE-CICAs in ion recognition was investigated; in particular, HBPE-CICA2 exhibited remarkable selectivity for Fe3+.
