MR-TADF liquid crystals: towards self assembling host-guest mixtures showing narrowband emission from the mesophase.

ABSTRACT: Creating (room temperature) liquid crystalline TADF materials that retain the photophysical properties of the monomolecular TADF emitters remains a formidable challenge. The strong intramolecular interactions required for formation of a liquid crystal usually adversely affect the photophysical properties and balancing them is not yet possible. In this work, we present a novel host-guest approach enabling unperturbed, narrowband emission from an MR-TADF emissive core from strongly aggregated columnar hexagonal (Col_h) liquid crystals. By modifying the DOBNA scaffold with mesogenic groups bearing alkoxy chains of different lengths, we created a library of Col_h liquid crystals featuring phase ranges >100 K and room temperature mesomorphism. Expectedly, these exhibit broad
