Abstract

In this study, we classified ortho‐phenylene‐naphthylene oligomers into three types II, III, and IV based on the sequence of phenylene and naphthylene units. Type II has an alternating sequence of phenylene and naphthylene units, type III has a phenylene‐naphthylene‐phenylene repeating structure, and type IV has a naphthylene‐phenylene‐naphthylene repeating structure. While type II has been studied in detail, there have been few reports on types III and IV. We report on the synthesis and photophysical properties of oligomers with type II, III, and IV substructures. Additionally, X‐ray crystallographic analysis confirmed that these oligomers adopt helical conformations.

苯并环法合成具有2,3 -二取代萘单元的高度精细螺旋分子

在这项研究中，我们将邻苯-萘低聚物根据苯和萘单元的顺序分为三种类型：II， III和IV。II型具有苯基和萘基交替序列，III型具有苯基-萘基-苯基重复结构，IV型具有萘基-苯基-萘基重复结构。虽然II型低聚物已经被详细研究，但III型和IV型的报道很少。我们报道了II型、III型和IV型亚结构低聚物的合成和光物理性质。此外，X射线晶体学分析证实这些低聚物采用螺旋构象。

期刊介绍： Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC) The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
