Synthesis and property of novel tellurium containing polymers

我们用AlCl3在60℃条件下，测定了TeCl4与某些芳香族化合物联苯、二苯基醚和二苯基硫化物在CHCl3中的缩合反应，反应时间为48 h，结果没有得到聚合物。用同样的方法研究了TeCl4与三苯基甲烷（TPM）的缩合反应，得到了相应的聚合物poly(Te-TPM), Mn′s = 2070 ~ 6860，收率为52 ~ 50%。该聚合物具有良好的溶解度、成膜性、热稳定性和高折射率等特点。在室温条件下，以吡啶为原料，双（4-羟基苯基）二氯化碲（HPT）与二氯化苯甲酰在二甲基乙酰胺中反应48 h，制得Mn = 6020 ~ 9200的相应聚酯，收率为76 ~ 83%。合成的聚酯具有良好的溶解度、成膜性、热稳定性和高折射率等特点。

We examined the condensation reaction of TeCl4 with certain aromatic compounds biphenyl, diphenyl ether, and diphenyl sulfide in CHCl3 using AlCl3 at 60 oC fro 48 h. As the result, no polymer obtained. Furthermore, condensation reaction of TeCl4 and triphenyl methane (TPM) was examined in the same way, to give corresponding polymers poly(Te-TPM)with Mn's = 2070 ~ 6860 in 52 ~ >99% yields. This polymer had good solubility, good film-forming property, high thermal stability, and high refractive index property. Furthermore, we examined the reaction of bis(4-hydroxy phenyl)tellurium dichloride (HPT) and phthaloyl dichloride using pyridine in dimethylacetamide at room temperature for 48 h, to afford corresponding polyesters with Mn's = 6020 ~ 9200 in 76 ~ 83% yields. The synthesized polyesters had good solubility, good film-forming property, high thermal stability, and high refractive index property.
