Structural features and optical properties of a carbazole-containing ethene as a highly emissive organic solid

Abstract

Carbazole derivatives are versatile materials especially for optoelectronic applications in light of their activity in both electronics and optics. To suppress the luminescence quenching effect in the condensed phase, we constructed a carbazole derivative with aggregation-induced emission characteristics. The highly emissive organic solid of carbazole-substituted ethene was facilely prepared and thoroughly tested. Through inspection of the geometric structure and packing motifs of the crystalline materials, the severely twisted conformation and the absence of strong intermolecular π–π interactions are found to account for the extremely high solid-state quantum yield. The highly blue emissive crystal fibers exhibit optical waveguide properties. Electroluminescence (EL) studies reveal the hole-transporting nature of the material.
