A novel calixarene‐containing hyperbranched aliphatic polyester incorporated with pendant europium complexes (H20‐Cal‐Eu) was synthesized and characterized by FTIR, UV, and element analysis. The polymer H20‐Cal‐Eu shows a glass‐transition temperature ( T g ) of 127°C, and a deposition temperature in the range of 280–600°C, as revealed by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), respectively. The investigation on its photoluminescence (PL) properties revealed that the polymer emitted a remarkably strong red luminescence. Furthermore, its half spectral bandwidth of the polymer film is only about 10 nm as determined from luminescence spectra, suggesting that the light is nearly monochromatic. It is proposed that the hyperbranched polymer (HBP) containing rare earth element exhibits great potential as a red light emitting material. Copyright © 2009 John Wiley & Sons, Ltd.
