The present work deals with the synthesis and photophysical, quantum mechanical, and lasing characterization of novel BODIPYs bearing amino and nitro groups at different positions in the core. The results emphasize the relevant role on the photophysical and lasing properties, not only of the attached functionality but also of the position in which is grafted, as well as the molecular structure of the indacene core. A wide part of the visible spectrum can be covered by the insertion of an amino group at position 3 (red shift) or 8 (blue shift). Furthermore, the electron withdrawing character of the nitro substituent induces intramolecular charge transfer processes, the efficiency of which depends on the position of the nitro group on the BODIPY core. All these experimental findings can be rationalized with the help of quantum mechanical calculations.
目前的工作涉及核心不同位置带有
氨基和硝基的新型 BODIPY 的合成以及光物理、量子力学和激光表征。结果强调了光物理和激光特性的相关作用,不仅包括所连接的官能团,还包括接枝位置以及苯并苯核的分子结构。在位置 3(红移)或 8(蓝移)插入
氨基可以覆盖大部分可见光谱。此外,硝基取代基的吸电子特性会诱导分子内电荷转移过程,其效率取决于硝基在 BODIPY 核心上的位置。所有这些实验结果都可以借助量子力学计算来合理化。
