“…The crosslinking of polymeric chains in aramids leads to polymers with improved thermal and mechanical properties, as demonstrated in some works [ 17 , 18 ]. Aromatic bithiazoles are well-studied compounds and are commonly used, regarding their biological properties, as antivirals against hepatitis B or HIV [ 19 , 20 ], and also in polymers as fluorescent chemosensors, and in polymer complexes with magnetic behavior [ 21 ], and in photovoltaics and thin-film transistors [ 22 , 23 , 24 ]. Also, thiazolo [4,5-d]thiazoles are recently studied as new domains for semiconductors and potential optoelectronic applications, showing intramolecular charge transfer [ 25 , 26 ].…”

We prepared high-performance aromatic copolyamides, containing bithiazole and thiazolo-thiazole groups in their main chain, from aromatic diamines and isophthaloyl chloride, to further improve the prominent thermal behavior and exceptional mechanical properties of commercial aramid fibers. The introduction of these groups leads to aramids with improved strength and moduli compared to commercial meta-oriented aromatic polyamides, together with an increase of their thermal performance. Moreover, their solubility, water uptake, and optical properties were evaluated in this work.

“…[16][17][18] The magnetization of these complexes was obviously influenced by the nature of the polymer and the difference of coordinating reactivity among the metal ions. These polymeric metal complexes could be employed for potential electrical, magnetic, and optical materials on appropriately choosing the constituent molecules.…”

The preparation and magnetism of two supramolecular polymeric complexes, DABT/PAA-Ni 2þ and DABT/PAA-Cu 2þ , which were obtained via electrostatic interactions of 2,2 0 -diamino-4,4 0 -bithiazole (DABT), poly(acrylic acid) (PAA), and transition metal ions (Cu 2þ or Ni 2þ ) were described. FTIR, 1 H NMR, and elemental analysis were used to characterize the structures of the obtained supramolecular polymer and the corresponding complexes. The corresponding multilayer films were also constructed on the quartz substrate. UV-vis spectra and AFM images were applied to characterize these films. The result indicates a process of uniform assembling. The magnetic behavior was examined as a function of magnetic field strength at 4 K and as a function of temperature (4-300 K). It was found that DABT/PAA-Ni 2þ exhibits a ferromagnetic property with a high value of relative saturation magnetization, while DABT/PAA-Cu 2þ shows a special magnetic property different from the typical magnet.
