Azulene-fused polycyclic aromatic hydrocarbons (PAHs) were synthesized from commercially available azulene in four steps. The resulting azulene conjugates exhibited significantly narrow HOMO-LUMO bandgaps with high air stability, confirmed by photophysical study. Introduction of azulene also enabled the unique reversible stimuli-responsiveness even with the weak acid and base, which can potentially control the degree of conjugation and optoelectronic properties by simple acid-base and redox processes.
从市售的薁合成了薁稠合多环芳烃 (PAH)，共四步反应。通过光物理研究证实，所得薁缀合物具有显著变窄的 HOMO-LUMO 能隙和高空气稳定性。薁的引入还赋予了独特的、对酸碱刺激的可逆响应性，即使是弱酸和弱碱也能实现，这有可能通过简单的酸碱和氧化还原过程来控制共轭度和光电性质。
