The synthesis and properties of a novel class of ortho-dialkylamino-substituted semisquaraines are described. The exceptionally low reactivity of the investigated compounds is caused by an intramolecularhydrogenbond as evidenced by experimental and computational studies. Although this constitutes the reason for our failed attempts to prepare poly(m-phenylene-alt-squaraine)s, the discovered influence
描述了新型的邻-二烷基氨基取代的半方胺的合成和性质。实验和计算研究证明,所研究化合物的异常低反应性是由分子内氢键引起的。尽管这构成了我们的失败的尝试的聚制备的原因(米-亚苯基- ALT -squaraine)类,氢键对这些半方酸菁的光物理性质的发现影响提供了一种用于传感器设计一个有前途的新基序。
