摘要：

A convenient one-pot, two-step methodology was developed for the transformation of readily available planar naphthoquinone derivatives into structurally complex indole-fused nitrogen heterocycles under aerobic conditions. The appropriate structural design in the synthetic protocols offered an opportunity to obtain deep red emitting solid-state fluorescence materials. Mechanistic studies revealed that atmospheric oxygen plays a crucial role in the aforementioned transformation.
