有机/无机杂化钙钛矿材料是一种综合性能良好的有序复合光电材料。选择具有较大共轭的咔唑类铵盐作为杂化钙钛矿的有机组分,合成氯化锌基杂化钙钛矿[(C6H4)2N(CH2)6NH3]2ZnCl4(N6AHMC-ZnCl4)。发现在该杂化钙钛矿材料中,由于有机/无机协同增强作用,使得该材料在紫外光区239nm、265nm、298nm、336nm和351nm处有较强的吸收峰,在分解温度为243℃条件下的失重率为5%,具有较好的热性能。
Organic-inorganic hybrid perovskite material are ordered high-performance photoelectric materials.Carbazole derivative amine salt with long conjugated chain was selected to synthesize ZnCl2 based hybrid perovskite [(C6H4)2N(CH2)6NH3]2ZnCl4.(N6AHMC-ZnCl4).The result showed that this perovskite material had strong absorption peak in the ultraviolet region located in 239nm,265nm,298nm,336nm and 351nm respectively.At the decomposition temperature of 243℃,the weight loss rate of material was 5%,because of the organic/inorganic coordination enhancement absorption effect,demonstrating a promising application prospect in the ultraviolet detecting field.
