A new class of π-conjugated organic fluorophores containing a 6-phenanthro[4,5-]pyreno[4',5':4,5]imidazo[1,2-]azepin-6-one core was synthesized by a facile one-pot condensation method. The molecular structures and solid-state packing properties of these compounds were investigated by X-ray single crystallographic analysis. UV-vis absorption and fluorescence spectroscopic studies disclosed interesting mechanofluorochromic properties in the solid state and highly sensitive acidochromic behavior in the solution phase.
一类新型的π共轭有机荧光团，含有一个 6-菲并[4,5-]吡咯并[4',5':4,5]咪唑并[1,2-a]氮杂卓-6-酮核心，通过简便的一锅缩合方法合成。通过 X 射线单晶结构分析研究了这些化合物的分子结构和固态堆积性质。紫外可见吸收和荧光光谱研究揭示了它们在固态中的有趣机械变色性质和在溶液相中的高灵敏的酸致变色行为。
