Synthesis, Characterization, and Properties of Diazapyrenes via Bischler–Napieralski Reaction

Via Bischler–Napieralski cyclization
of amide precursors
as the key step, a series of diazapyrene derivatives were designed
and successfully synthesized. Their crystal structures, optoelectronic
properties, and acid-responsive feature were investigated, which demonstrated
that the doping of nitrogen atoms to the pyrene framework remarkably
modulates their physical and chemical properties.

以 Bischler–Napieralski 环合反应作为关键步骤，设计并成功合成了一系列二氮杂芴衍生物。对其晶体结构、光电子性质及酸响应特性进行了深入研究，结果表明，将氮原子掺杂至芴骨架中显著调节了其物理与化学性质。
