“…Other groups also prepared some HBPs through different synthetic strategies. [173][174][175][176][177][178][179] In comparison with the normal linear NLO polymers, these HBPs demonstrated much better performance, confirming the importance of 3D topological structure in the NLO field once again.…”

As one kind of important functional material, those with advanced optical, electrical and magnetic characteristics have attracted increasing attention due to their essential and irreplaceable role in the daily life of humans. In particular, optical, electrical and magnetic hyperbranched polymers (HBPs) exhibit some unique properties, partially derived from their highly branched topological structures. This review summarizes the recent progress in the field of functional HBPs and their application in optics, electronics and magnetics, including light-emitting polymers, nonlinear optical materials, chemosensors, solar cells, magnetic materials, etc., and also gives some outlooks for further exploration in this field at the end of this paper.

“…7 The use of fluorinated species can also aid in the formation of non-covalent interactions that improve the organization of the molecules in the crystal phase and thus the electrooptic properties. 4,8 For these reasons, a notable number of studies were devoted to the synthesis of polyfluorinated arylenes. [9][10][11][12] Recently, a versatile method for construction of fluorinated poly(aryl thioethers) was developed based on organo-catalyzed nucleophilic aromatic substitution of silyl-protected dithiols.…”

“…Hyperbranched polymers usually have good solubility and low viscosity compared to the linear analoges. [1][2][3][4][5][6][7][8][9][10][11][12] Combining of chemically stable amide bonds with hyperbranched structures not only retained excellent thermal and flame-resistant properties of aromatic polyamides, but also decreased melt viscosity and excellent solubility which improved the processability. [13][14][15][16][17][18][19][20] Moreover, introduction of flexible aliphatic units into the main chain is another method to improve the processability of aromatic polyamides.…”

Phosphorus-containing hyperbranched aromatic-aliphatic polyamides are prepared via direct polymerization of triacid (B 3 ) with different diamines (A 2 ), which for improving the processability of aromatic polyamides while keeping exellent thermal and mechanical property. The triacid (B 3 ), tris(2-carboxyethyl)phosphine oxide (TCEPO), is synthesized from tetrakis(hydroxymethyl)phosphonium sulfate and its structure is verified by Fourier transform infrared, 1 H, 13 C and 31 P NMR spectroscopy. Then, the polycondensation reaction of TCEPO with p-phenylene diamine, 4,4′-oxyphenylene diamine and 4,4′-methylenedianiline result in three phosphorus-containing hyperbranched aromatic-aliphatic polyamides, and the degree of branching is found between 0.66 and 0.71. Gel permeation chromatography measurement reveal that all hyperbranched aromatic-aliphatic polyamides have moderate number-averaged molecular weights and narrow molecular weight distribution. The Dynamic mechanical thermal analysis results show all polymers have two glass transition temperatures (T g ) in the temperature range 85.3-128.0°C and have high storage modulus about 1.52-3.19 GPa at 50°C. The TGA results reveal the initial degradation temperatures (T 5 ) and the temperatures for 10% gravimetric loss (T 10 ) for the hyperbranched aromatic-aliphatic polyamides are in the range of 214-250 and 256-333°C, and the maximum decomposition temperatures (T m ) are about 500°C, and also the char yields of polymers at 850°C are about 39.4-48.4%, which indicate good thermal stability.
