Circularly polarized room-temperature phosphorescence in microcrystals via aggregation-induced chirality transfer

Chiral luminophore Ben-2Chol self-assembles into micrometer sheets in aggregates, achieving CPF. Its fibrous microcrystals show CPRTP with opposite polarization, g lum of +6.0 × 10 −3 (blue) and +1.0 × 10 −3 (yellow-green), and 41.7 ms lifetime.
