在本文中，通过调节反应单体的进料摩尔比，使用1,3,5-苯三羧酸和2,6-二氨基苯并[1,2-d]，合成了两种具有不同端基的新型含苯并双噻唑的超支化聚酰胺。：4,5-d']双噻唑为单体，多磷酸为溶剂，和催化剂。合成的超支化聚合物的分子结构通过¹ H-核磁共振（NMR）分析，¹³ C-NMR分析和傅立叶变换红外分析来推测。羧基端基聚合物HB-COOH的M _n，M _w和DB分别为3264 g / mol，3350 g / mol和44.1％，多分散度为1.03。在中号_Ñ，氨基端聚合物HB-NH _2的M _w和DB分别为3340 g / mol，3420 g / mol和41.7％，多分散度为1.02。在30°C至800°C的温度范围内，HB-NH ₂的热稳定性高于HB-COOH。这两种含苯并双噻唑的超支化聚酰胺完全无定形，可溶于DMSO。他们的DMSO溶液显示出很强的蓝色荧光。HB-NH ₂的荧光强度高于HB-COOH。所制备的聚合物潜在地在蓝色发光和显示领域有用。©2016 Wiley Periodicals，Inc.

Synthesis and properties of novel benzobisthiazole‐containing hyperbranched polyamides derived from 2,6‐diaminobenzo[1,2‐d:4,5‐d']bisthiazole

In this article, two novel benzobisthiazole‐containing hyperbranched polyamides with different end groups were synthesized, by adjusting the feed molar ratio of the reaction monomers, using 1,3,5‐benzenetricarboxylic acid and 2,6‐diaminobenzo[1,2‐d:4,5‐d']bisthiazole as monomers, polyphosphoric acid as solvent, and catalyst. The molecular structure of the synthesized hyperbranched polymers were speculated by ¹H‐nuclear magnetic resonance (NMR) analysis, ¹³C‐NMR analysis, and Fourier transform infrared analysis. The M_n, M_w, and DB of the carboxyl terminated polymer HB‐COOH are 3264 g/mol, 3350 g/mol, and 44.1%, respectively, with a polydispersity of 1.03. The M_n, M_w, and DB of amino terminated polymer HB‐NH₂ are 3340 g/mol, 3420 g/mol, and 41.7%, respectively, with a polydispersity of 1.02. The thermal stability of HB‐NH₂ was higher than HB‐COOH in the range of 30 °C–800 °C.These two benzobisthiazole‐containing hyperbranched polyamides were completely amorphous and soluble in DMSO. Their DMSO solutions exhibited strong blue fluorescence. The fluorescent intensity of HB‐NH₂ was higher than HB‐COOH. The prepared polymers were potential useful in the area of blue light emitting and display. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43453.
