摘要
以苯甲醛、苯乙酮为起始原料,经羟醛缩合、迈克尔加成、成环、氟硼络合得到氮杂氟硼二吡咯。通过氧化反应得到azaBODIPY二聚体化合物。对其进行紫外吸收光谱测试,在CH 2Cl 2中最大紫外可见吸收峰在700 nm附近,相比于单体红移50 nm。溶剂选择二甲苯,将化合物配制成质量浓度为30μg/mL的溶液,该溶液在波长660 nm、功率密度0.9 W/cm 2的近红外激光照射下可以从22.4℃升温至47.2℃。通过计算,二聚体的光热转换效率为72.9%。通过多次循环升温效果保持一致,说明具有较好的光热稳定性。氮杂氟硼二吡咯二聚体可以作为近红外光热材料。
In this paper,benzaldehyde and acetophenone were used as starting Materials to prepare azaBODIPY by aldol condensation,Michael addition,ring formation and fluoroboride complexation.The dimer of azaBODIPY compound was obtained by and oxidation reaction.Then we tested the UV-visible absorption spectrum,the maximum absorption peak redshifted about 50 nm compared with the monomer located at 700 nm.In xylene,the dimer with a concentration of 30μg/mL can be heated from 22.4℃to 47.2℃under the irradiation of the infrared laser with a wavelength of 660 nm and a power density of 0.9 W/cm 2.The photothermal conversion efficiency of the dimer is 72.9%.The effect of temperature rise through multiple cycles is consistent,indicating that it has good photothermal stability.The results indicated the dimer of azaBODIPY can be used as NIR photothermal material.
