With the goal of preparing luminescent, fully conjugated Schiff base macrocycles, a series of precursors based on benzene, phenanthrene, and triphenylene with formylhydroxy functionalization have been prepared and characterized. The condensation of these compounds with substituted phenylenediamines to afford conjugated [2+2] or [3+3] Schiff base macrocycle has been investigated. Although the [3+3] Schiff base macrocycles could not be isolated, two new soluble and luminescent [2+2] Schiff base macrocycles with N2O2 binding pockets have been prepared and characterized.Key words: Schiff base, macrocycle, condensation, salicylaldehyde, conjugated.
为了制备发光的全共轭席夫碱大环,我们制备了一系列基于苯、
菲和三亚苯的甲酰羟基官能团前体,并对其进行了表征。研究人员研究了这些化合物与取代的
苯二胺缩合生成共轭 [2+2] 或 [3+3] 席夫碱大环的过程。虽然未能分离出[3+3] 希夫碱大环,但制备出了两种新的可溶性发光[2+2] 希夫碱大环,并对其进行了表征:希夫碱 大环 缩合
