Abstract
Well-defined crystalline condensed superstructures of conjugated molecules are required for light-emitting optoelectronic devices. Similar to symmetry breaking in nature, stereoisomerism can programmatically and extraordinarily control molecular crystallization and provide access to unexpected optoelectronic behaviors. Here, we demonstrated supramolecular chiral oligofluorenols (2O8-DPFOH-SFX) with a hierarchical ordered structure and ultrastable crystalline-enhanced emission by controlling the molecular stereoisomerism. The raceme displays a highly ordered and uniform structure with molecular-level orientation, but no transition was observed for the mesomer. This well-defined architecture s..
