Novel azulene building blocks, prepared via the cycloaddition of thiophene-S,S-dioxides and fulvenes, allow for incorporation of the seven-membered ring of the azulene nucleus directly into the backbone of conjugated materials. This unique mode of incorporation gives remarkably stable, stimuli-responsive materials upon exposure to acid. This simple doping/dedoping strategy provides for effective optical
通过噻吩-S、S-二氧化物和富烯的环加成反应制备的新型菘烯结构单元允许将茚核的七元环直接结合到共轭材料的主链中。这种独特的掺入方式在暴露于酸时提供了非常稳定的刺激响应材料。这种简单的掺杂/去掺杂策略提供了有效的光学带隙控制和开/关荧光切换,让人想起聚苯胺。
