Abstract

In this article, we present several organic synthetic way to synthesize a family of five polyaromatic molecules based on a cyclophane core. Our strategies revolves around palado-catalyzed substitution on a [2.2]paracyclophane (pCp) building block. Direct formation of a cyclophane was also employed for two molecules. The polyaromatic nature of the cyclophane library we synthetized made them good fluorophores candidate, we hence performed full photophysical characterization (Absorption, Emission, TCSPC) in different solvent as well as embed in polystyrene films. We evaluate how the cyclophane moiety influence their photo physical properties compared to their corresponding homologues without pCp core, demonstrating greater stoke shift and intramolecular exciplex behavior. The general behavior among cyclophanes was also compared and show solvent dependent properties as well as consistency of the photophysics between toluene and polystyrene matrix.

多芳环烷的设计及其相关光学性质。
本文介绍了几种以环烷为核心合成5个多芳分子的有机合成方法。我们的策略围绕palado催化取代[2.2]对环己烷(pCp)构建块。两个分子也采用了直接形成环烷的方法。我们合成的环烷文库的多芳香族性质使其成为良好的候选荧光团,因此我们在不同的溶剂中进行了全面的光物理表征(吸收,发射,TCSPC)以及在聚苯乙烯薄膜中的嵌入。我们评估了环烷部分如何影响它们的光物理性质,与没有pCp核心的相应同系物相比,显示出更大的stoke位移和分子内外络合物行为。还比较了环烷的一般行为,并显示出溶剂依赖性以及甲苯和聚苯乙烯基质之间的光物理一致性。

期刊介绍: ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
