At first, a n unsaturated monomer bearing luminescence group, acryloyl fluorescein was synthesized from fluorescein and acryl oyl chloride by simple method and was identified by IR, MS and 1H NMR spectra. The homopolymer of monomer was obtained with solution polymerization and the average molecular weights obtained was not high and the weight average molecular weigh M w ) was 1.93 ×10 44. The water-soluble copolymer of acryloylfluorescein and acrylamide, poly(acryloylfluoresceinacryloylfluorescein-co-acrylamide), was synthesized with thermal initiator and was characterized by the method of IR, UV-vis and DSC. The luminescence behaviors of monomer and polymers were explored and the pH and temperature dependence of fluorescence of copolymer were investigated in detail. The results showed that copolymer had an excellent linear response between relative fluorescence intensity and temperature in the range of 0-60 °C and had a nonlinear response from pH 4.7 to 9.8 between relative fluorescence intensity and pH. Thus, the copolymer was promising polymeric materials for bifunctional probe for temperature and pH based on fluorescence..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
