摘要
（薁（Azulene）作为一种非苯系芳香化合物，因其独特的非交替拓扑结构和偶极矩，在构筑具有特殊光电性能的多环芳烃（PAHs）材料中引起了广泛关注。本论文利用课题组已合成的5,6-薁炔前体，分别与1-(2-碘苯基)萘、3,6-二苯基-1,2,4,5-四嗪、1,8-二(2-呋喃基)萘、2-苯基咪唑并[1,2-A]吡啶四种底物反应，成功制备了四种新型薁稠合多环芳烃分子。通过紫外-可见吸收光谱（UV-Vis）和荧光光谱（Fluorescence）测试表明，由于薁单元的引入，这些化合物表现出独特的光学性质，包括显著的红移吸收和可调控的发射行为。本研究不仅拓展了薁炔化学的应用范围，也为设计合成新型有机光电功能材料提供了新的思路。
Abstract
Azulene, a non-benzenoid aromatic compound, has attracted considerable attention for constructing polycyclic aromatic hydrocarbons (PAHs) with unique optoelectronic properties owing to its distinctive non-alternant topology and inherent dipole moment. In this work, four novel azulene-fused polycyclic aromatic hydrocarbons were successfully synthesized by reacting a previously prepared 5,6-azulenyl alkyne precursor from our group with four different substrates: 1-(2-iodophenyl)naphthalene, 3,6-diphenyl-1,2,4,5-tetrazine, 1,8-bis(2-furyl)naphthalene, and 2-phenylimidazo[1,2-a]pyridine. UV-Vis absorption and fluorescence spectroscopy revealed that incorporation of the azulene unit endows these compounds with distinctive optical properties, including markedly red-shifted absorption and tunable emission behavior. This study not only broadens the scope of azulene-alkyne chemistry but also offers new strategies for the design and synthesis of advanced organic optoelectronic materials.关键词
