摘要
本文选取9-乙酰基蒽为主体,具有不同官能团的有机分子为客体形成新的共晶化合物,使其光物理性能(如波长,发光颜色,寿命,量子产率等)得以明显改变。同时产生了具有上转换和聚集诱导发光等新的现象。此外,周期性密度泛函理论计算也进一步证明客体的选择对共晶结构的影响,为研究新型光功能共晶材料的结构-性能关系提供理论前提和应用依据。
In this work, we report the tunable photoemission of a 9-acetylanthracene(ACA) chromophore based on the formation of two component molecular cocrystals with four different co-assembled building blocks, which present wide-range tunability of luminescence properties(such as wavelength, color, fluorescence lifetime, photoluminescence quantum yield). In addition, two-photon emission and aggregation induced emission(AIE) properties can be further obtained for ACA-based cocrystals, which are absent for the pristine ACA solid. Moreover, density functional theory(DFT) calculations suggest that the introduction of TCB can largely influence the energy level structures and orbital distributions of the ACA chromophore in the two-component crystals. Therefore, by the combination of experimental and theoretical studies on the molecular cocrystals, this work provides a foundation of theory and application for the development of new type optical functional materials.
