triazapyrene cores have π-stack packing. Incorporating nitrogen atoms into the pyrene framework bathochromically shifted the lowest energy onsets of the absorption bands and increased the first reduction potentials. The nitrogen-containing pyrenes showed fluorescence with a weaker intensity (Φf = 0.041–0.12) than that of the parent pyrene. The number and position of nitrogen atoms influenced the extent of these
我们开发了一个短程合成2,4,10-三氮杂戊烯,涉及两个连续的CH取代:Pd通过CH芳基化催化的交叉偶联反应,然后进行分子内Cu催化的CH H官能化。该方法已成功地用于制备4,10-二氮杂-,1,4,10-三氮杂草和1,3,4,10-四氮杂戊烯。5,9-二(4-甲基苯基)-2,4,10-三氮杂ap的晶体结构分析表明,平面三氮杂yr核具有π堆积堆积。将氮原子掺入bath骨架中,发生了红移,从而使吸收带的最低能量起始点发生位移,并增加了第一个还原电位。含氮果核显示具有较弱强度的荧光(Φ ˚F= 0.041–0.12)。氮原子的数量和位置影响了这些影响的程度。
