在过去的二十年里，pi共轭有机化合物因其在液晶、发光、非线性光学材料和自组装等领域的潜在应用而引起了人们的广泛关注。在需要电子转移的情况下，将杂芳基引入到聚酰亚胺扩展体系中尤其有用，这是一种修饰、有时还增强先进“电光”性能的方法。在pi共轭材料中，氮杂环如嘧啶，由于其芳香性、强吸电子特性、高度偶极相互作用和对pH的敏感性，在众多不同的应用中呈现出被有机材料所要求的特性。本文综述了此类分子结构及其应用。
In the past two decades, pi-conjugated organic compounds have attracted much attention due to their potential applications in various fields such as liquid crystals, light-emitting, and nonlinear optical materials and self assembling. Introduction of heteroaryl moieties into pi-extended systems are particularly useful where electron transfer is necessary and is a way to modify and sometimes enhance properties of advanced "electro-optic". In pi-conjugated materials, azaheterocycles such as pyrimidine, which owing to its aromaticity, its strong electron-withdrawing character, its high dipolar interaction and its pH sensibility, presents the requested characteristics to be incorporated in organic materials in view of numerous and various applications. Such molecular architectures and their applications are reported in this review.
