We report on the design, optimized synthesis, and characterization of a thiophene–phthalimide based small molecule. We show that microwave irradiation is a useful technique to accelerate direct arylation cross-coupling reactions, and that the thiophene–phthalimide architecture can lead to face-to-face intermolecular π-stacking, resulting in pronounced blue shifts in the absorption maximum upon a solution
我们报告了基于噻吩-邻苯二甲酰亚胺的小分子的设计,优化合成和表征。我们表明,微波辐射是加速直接芳基化交叉偶联反应的有用技术,噻吩-邻苯二甲酰亚胺结构可导致面对面的分子间π堆积,从而导致溶液中吸收最大值的明显蓝移到凝聚态转变。
