4-functionalized dipicolinic acid, ester, or amide featuring π-conjugated substituents such as donor-(phenyl or fluorenyl)-acetylene groups have been synthesized. Four crystallographic structures are reported. The influence of the substituent position, the nature of the donor group, and the conjugated backbone as well as the role of the pyridinic side arms on the absorption and emission properties are studied and
已经合成了一系列具有π-共轭取代基如供体-(苯基或芴基)-乙炔基的2,6-和4-官能化的二吡啶甲酸,酯或酰胺。报告了四个晶体学结构。在TD-DFT计算的基础上,研究和讨论了取代位置,给体基团的性质和共轭主链的性质以及吡啶酮侧臂对吸收和发射性质的影响。
