  Fabrication and characterization of novel high-performance fluorinated polyimides with xanthene pendent architecture: Study of thermal, photophysical, antibacterial and heavy metal ion adsorption behavior

  摘要：

  Two series of new fluorescent polyimides (PIs) with different functional groups such as flexible ether linkages, substituted imidazole, photoactive xanthene pendant, and electron withdrawing CF3 groups were prepared using novel monomers and three commercially available dianhydrides. The structures of two diamines and PIs were fully characterized by elemental analysis, FT-IR and H-1 NMR spectroscopy. The prepared polymers were amorphous with inherent viscosity ranged from 0.38 to 0.66 dL/g, they were readily soluble in a variety of organic solvents and tough transparent films were prepared by solution casting method. These polymers showed useful level of thermal stability having high glass transition (T-g) (235-303 degrees C) and 10% weight loss (402-498 degrees C) temperatures with more than 62% residue at 800 degrees C under N-2. They exhibited strong UV-vis absorption in solutions and in films. Photoluminescence efficiency was affected by the chemical structure of the polymers and their quantum yields ranged from 7 to 21%. The antibacterial activity of diamines and two polymers were investigated against Grain positive and Gram negative bacteria. Also, the prepared PIs were investigated for the removal of heavy metal ions such as Cr3+, Pb2+, Hg2+, Cd2+ and Co2+ from aqueous solutions at pH 7-8. (C) 2016 Elsevier B.V. All rights reserved.

The surface hydrophobicity was changed by adjusting the mass and type of nanoparticles. Thus, this work provided a simple way to improve the photoluminescence effect by introducing the nanoparticles.

  A novel aromatic trifluoromethylated diamine containing various functional groups was synthesized and characterized by using different spectroscopic techniques. The diamine was polymerized with various dianhydrides in a green media of ionic liquid (IL) without using NMP-pyridine-acetic anhydride. The poly(ether-imidazole-imide) (PEII)s were obtained in good yields (80-96%) with moderate viscosity (0.33-0.67 dL g(-1)) in a shorter reaction time (10 h vs. 36 h) in IL The resulting polymers were fully characterized and their properties such as solubility, viscosity, crystallinity, thermal, photophysical, and electrochemical behavior were investigated. They were amorphous and showed excellent solubility even in common organic solvents, such as chloroform and m-cresol, with ability to form tough and flexible films. The films were colorless and exhibited high optical transparency, with the UV cutoff wavelength in the range 304-337 nm and the wavelength of 80% transparency in the range 375-400 nm. Furthermore, they also possessed good thermal and thermo-oxidative stability with 10% weight loss temperatures (T-10%) in the range 441-528 degrees C in N-2 atmosphere and in the range 382-494 degrees C in air. The glass transition temperatures of all polyimides are in the range 204-302 degrees C.Their electrochemical behavior was also studied by using adsorptive stripping cyclic voltammetry and impedance spectroscopy on the multi-walled carbon nanotube-modified glassy carbon electrode.
