Paper Title:
Synthesis and Photoproperties of Fluorescent Brighteners Modified by Polyaminamide
  Abstract

One of amino compounds of traditional fluorescent brighteners with polyaminamide was replaced and new triazinyl aminostilbene fluorescent brightener was modified by polyaminamide which synthesized through three-step condensation reaction. The molecular structures were characterized by IR spectrum and photoproperties in aqueous and ethanol were studied by ultraviolet absorption spectra, fluorescence emission spectra, photochemical stability and paper coating application test. The results show that the light stability and fluorescence quantum yield of polyaminamide fluorescent brighteners (PFBs) were improved obviously, which compared with the traditional FBs, such as VBL, and the whitening performance of paper coating enhanced and used widely. Meanwhile, the photophysics and photochemical properties of triazene-stilbene fluorescence brighteners are markedly determined by solvent polarity.
