摘要
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 1; 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.
