Abstract
In this work, water-soluble semiconductor quantum dots (QDs) showing induced circularly polarized luminescence (CPL) in an organic-inorganic coassembled hydrogel were demonstrated. Achiral QDs can be encapsulated into chiral peptide dendron hydrogel through the procedure of cogelation. These cogels display intense induced circularly polarized emission. In addition, the direction of CPL property of QDs cogels could be regulated by the supramolecular chirality of hydrogels. Our findings reveal that the emergence of CPL achiral QDs can be trigged by the chirality transfer in a multiple component dendron hydrogel system. This study has given a new understanding into the design of functional chiroptical materials.
