摘要:以5-脱氢枞酸三苯胺-噻吩-2-甲醛与3,5-双(三氟甲基)苯乙腈为原料,分别在常温和加热回流的条件下反应,得到2个脱氢枞酸三芳胺基丙烯腈化合物:甲基(Z)-6-((4-(5-(2-(3,5-双(三氟甲基)苯基)-2-氰基乙烯基)噻吩-2-基)苯基)(4-甲氧基苯基)氨基)-7-异丙基-1,4a-二甲基-1,2,3,4,4a,9,10,10a-八氢菲-1-羧酸盐(2)和二甲基6,6'-(((1-氰基乙烯-1,2-二基)双(噻吩-5,2-二基))双(4,1-苯撑)双(4-甲氧基苯基)氮杂二烯基)(E)-双(7-异丙基-1,4a-二甲基-1,2,3,4,4a,9,10,10a-八氢菲-1-羧酸盐)(3)。探讨了化合物2和3的紫外吸收光谱、荧光发射光谱、溶致变色效应、聚集诱导发光(AIE)特性、热稳定性及电化学性能,并通过理论计算对其结构与性能的关系进行了进一步分析。研究结果表明:与三芳胺基丙烯腈化合物相比,引入脱氢枞酸骨架后,化合物表现出更大的斯托克斯位移、固体状态下更长的红光发射;化合物2表现出AIE特性,而化合物3不具有AIE特性;这两个化合物均具有较好的热稳定性和形态稳定性。脱氢枞酸骨架的引入使得2和3获得了更高的HOMO、LUMO能级,以及窄的带隙值。
Compounds methyl(Z)-6-((4-(5-(2-(3,5-bis(trifluoromethyl)phenyl)-2-cyanovinyl)thiophen-2-yl)phen-yl)(4-methoxyphenyl)amino)-7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate(2)and dimethyl 6,6'-(((1-cyanoethene-1,2-diyl)bis(thiophene-5,2-diyl))bis(4,1-phenylene))bis((4-methoxyphen-yl)azanediyl))(E)-bis(7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate)(3)were obtained simply by mixing 5-(dehydroabietic acid triarylamine)-thiophene-2-carbaldehyde and 3,5-bis(trifluoromethyl)phenylacetonitrile at room temperature and 100℃,respectively.The UV-Vis absorption spectra,fluorescence emission spectra,solvatochromism effect,aggregation-induced emission(AIE)characteristics,thermal stability and electrochemical performance of compounds are studied,and the relationship between their structure and performance is further studied through theoretical calculations.Compared with triarylamine-based acrylonitrile compounds,after introducing the dehydroabietic acid skeleton,the compounds show a larger stokes shift and longer red light emission in the solid state.2 exhibits AIE characteristics,while 3 does not have AIE characteristics.Both of the two compounds have good thermal stability and morphological stability.2 and 3 have higher highest occupied molecular orbital(HOMO),lowest unoccupied molecular orbital(LUMO)energy levels and narrow band gap,due to the introduction of dehydroabietic acid skeleton.
