A–π–D–π–A carbazole derivatives with remarkable solvatochromism and mechanoresponsive luminescence turn-on

Abstract

Two A–π–D–π–A carbazole derivatives differing in <italic>N</italic>-hexyl and <italic>N</italic>-isooctyl substituents were developed. They exhibited a prominent solvatochromic effect and luminescence turn-on characteristics under mechanical force stimuli.
