Mechanical and Thermal Properties of Polyquinolines

Polyimides and Other Heteroaromatic Polymers

“…41,42 Two types of polyimides have been developed: (i) condensation polyimides (20), linear polymers coming from the reaction between bis(o-dicarboxylic acid) derivatives and diamines; and (ii)addition polyimides, mainly bismaleimide (21) and bisnadimide (22), which react during the processing to give cross-linked networks.~- They are used in various industries, such as electrical insulation, space, aviation, electronics and industries using gas permeation.…”

Polyquinolines: A class of rigid‐chain polymers

“…The hydrochloric acid was removed in uucuo, and the resultant violet oil was placed under reduced pressure for an additional 8 hr, giving 19.8 g (73%) of a clear violet oil. HI-nmr (CCl4): 6 2.15 (s, 3, CH3), 6 6.7-7.2 (m, 4, aromatic), 6 12.2 (s, 2, OH). 31P-nmr ( 1 .O g m-cresyl phosphate in 2.4 ml m-cresol): 6 5.4 relative to H3P04.…”

An aza-Diels–Alder route to quinoline-based unnatural amino acids and polypeptide surrogates

“…1,2,[11][12][13][14][15][16][17][18][19][20][21] These polymers have demonstrated a number of highly desirable features, including tunable electronic properties, chemical inertness, mechanical robustness, thermal stability, and facile processability. [1][2][3][4][21][22][23] Additionally, quinoline-decorated oligopeptides and quinoline-containing oligoamides have been frequently prepared via the conjugation of quinoline derivatives to amino acids or via the iterative coupling of small molecular building blocks on solid support. [24][25][26][27][28] These oligopeptides and oligoamides have exhibited various favorable characteristics, including sequence modularity, resistance to proteolytic degradation, ready cellular uptake, controllable conformational stability, and compatibility with a wide range of solvents.…”
