In addition, L can also selectively identify solvent CH2Cl2 by inducing larger blue-shift in wavelength and increase in fluorescence intensity, which means that it may be used as an indicator for monitoring trace amount of CH2Cl2. The potent applicantions for sensor L were also investigated and ...
To further prove that the PDs retain the properties of the polymer, FTIR spectra and 1H NMR were analyzed for their molecular structures and functional groups. The absorption peak at 3284 cm−1 and 3080 cm−1 were attributed to the stretching vibration of –NH2, presenting in both 2.0G ...
