Crafting 1,4-diaryl spirobifluorene hosts in OLEDs via interannular C–H arylation: synergistic effects of molecular linearity and orthogonality

Abstract

In this work, we present a design concept of introducing linear structures into the orthogonal configuration of 9,9'-spirobifluorene (SBF), aiming to enhance carrier mobilities while maintaining high triplet energies (ET),...
