新型三蝶烯衍生物2,3,6,7-四甲基-9,10-邻萘基蒽的合成
2013年
目的基于2,3,6,7-四甲基蒽合成了一种新型三蝶烯衍生物2,3,6,7-四甲基-9,10-邻萘基蒽。方法以2,3,6,7-四甲基蒽和1,4-环氧-1,4-二氢萘为原料,通过Diels-Alder反应和脱水作用合成目标产物,对产物进行表征。结果过量的2,3,6,7-四甲基蒽与1,4-环氧-1,4-二氢萘反应,在VAcOH∶VAcOAc=2∶1的混合脱水剂作用下合成了目标产物,表征结果显示化合物结构正确。结论利用廉价易得的原料简便合成了新型三蝶烯衍生物2,3,6,7-四甲基-9,10-邻萘基蒽,它可以作为潜在的适用于聚酰亚胺合成的二酐单体。

Novel hyperbranched polyimides from 2,6,12-triaminotriptycene被引量:6
2008年
The monomer 2,6,12-triaminotriptycene was synthesized and the structure was confirmed by IR and 1H NMR spectra. Hyperbranched polyimides modified with different terminal groups were obtained from precursors, anhydride- and aminoterminated hyperbranched poly(amic acid)s from polymerization of A2 + B3 system. From gel permeation chromatograrn (GPC) characterization, representative products had high molecular weight. All polymers had good solubility in CHCl3, DMF and tetrahydrofuran (THF), and performed no detective Tgs in the range of 50-300 ℃ and high Tds above 455 ℃ when 5% weight loss.

SYNTHESIS AND CHARACTERIZATION OF FLUORINATED POLYAMIDES DERIVED FROM UNSYMMETRICAL DIAMINES CONTAINING THE PHTHALAZINONE MOIETY
2007年
A novel unsymmetrical fluorinated diamine monomer with kink non-coplanar heterocyclic structures, 1,2-dihydro- 2-(4-amino-2-trifluoromethyophenyo)-4-[4-(4-amino-2-trifluoromethyophenoxy)phenyo](2H)phthaoazin-1-oneo was prepared through the nucleophilic substitution reaction of 1-trifluromethyl-2-chloro-5-nitrobenzene with 1,2-dihydro-4-(4- hydroxyphenyl)(2H)phthalazin-l-one in the presence of potassium carbonate, followed by catalytic reduction with hydrazine and Pd-C. A series of new fluorinated polyarnides were synthesized by the phosphorylation polyamidation of the fluorinated diamine with various dicarboxylic acids. The prepared polymers were obtained in quantitative yields with moderately and high inherent viscosities (0.47-0.87 dL/g). They were all amorphous and readily soluble in various polar aprotic solvents such as N-methyl-2-pyrrolidone (NMP), N,N-dimethylformamide (DMF), N,N-dimethylacctamide (DMAc), pyridine (Py) and m-cresol at room temperature. These fluorinated polyamides have excellent thermal properties. The glass transition temperatures were all above 300℃. The 5% and 10% weight loss temperatures were in the range of 437-466℃ and 482-525℃ in nitrogen atmosphere, respectively.
