Summary:Through screening of a synthetic library a novel class of dihydropyrano[3,2-g]indolizine (DPI)-based solution-solid dual compounds with aggregation-induced emission characteristics (AIEgens) was discovered by A. Goel etal. and is reported in their Communication on page4527ff. The AIEgens operate by a restriction of intramolecular vibration (RIV) mechanism. A range of multicolor (red, yellow, green, and blue) solid-state luminogens was synthesized. Detailed analysis of the crystal structure of the DPIs revealed a well-defined set of noncovalent interactions (CHO and/or CHN), which blocked the motion of C sub(2)-flexure leading to RIV, thus promoting highly emissive behavior in the solid state.
