摘要 功能染料的J-型聚集体是一类重要的超分子材料并在诸多领域有广泛的应用。通过在氮杂氟硼二吡咯(Aza-BODIPY)染料核心结构的2,6-位引入尿嘧啶基团合成的Aza-BODIPY染料1,能够在双重氢键的作用下在甲基环己烷溶液中自组装形成J-型聚集体。该J-型聚集体的最大吸收波长位于768 nm,相比单体红移了47 nm。变温/变浓度紫外-可见吸收光谱研究表明,该J-型聚集体的形成符合协同自组装机理。利用透射电镜和激子耦合理论计算研究了J-型聚集体的形貌和分子排列结构。

Abstract: J-aggregates of functional dyes represent a class of important supramolecular material that have been applied widely in various fields. A novel boron-azadipyrromethene (aza-BODIPY) dye 1 appended with uracil groups on 2,6-positions was synthesized, which could self-assemble into nanofibrous J-aggregates in methylcyclohexane driven by intermolecular double hydrogen bonds. The maximum absorption wavelength of the J-aggregates of dye 1 located at 768 nm, which was bathochromically shifted for 47 nm compared with that of the monomers. Temperature/concentration-dependent UV/Vis spectroscopy demonstrated that the formation of J-aggregates of dye 1 followed the cooperative self-assembly mechanism. The morphology and molecular packing structure of J-aggregates were studied by transmission electron microscopy and exciton theory calculation.
