New blue‐emittingmaterials based on 1,2‐diphenylindolizine were designed and synthesized through a microwave‐assisted Suzuki coupling reaction. The photophysical, electrochemical, and thermal properties of the 1,2‐diphenylindolizine derivatives were investigated using UV–visible and fluorescence spectroscopy, cyclic voltammetry, thermogravimetric analysis, and differential scanning calorimetry.

Chromogenic compounds of normally colorless form are disclosed having the following structural formula: ##STR1## wherein E represents a six-membered aromatic or heterocyclic ring which may have an aromatic condensed ring and both the E ring and the condensed ring may be substituted, A represents an optionally substituted aminophenyl, indolyl, benzoindolyl, julolidinyl or kairolyl radical or the radical represented by B, and B represents a family of indolizine radicals. The compounds of this invention are eligible for use in pressure-sensitive and heat sensitive record materials and manifold marking systems.
A novel copper-catalyzed annulation of 2-alkylazaarenes with alpha,beta-unsaturated carboxylic acids has been accomplished. This reaction featuring C-H olefination and decarboxylative amination processes provides a concise access to C-2 arylated indolizines from simple and readily available starting materials.
