Chiral host
WebDec 24, 2024 · Chiral MOFs, which have numerous nanosized chiral helical channels, are appropriate chiral hosts to confine achiral chromophores. In this case, the size matches between the chiral cavities and achiral guests, interactions between the host and guest, and energy levels between the host MOFs and guest should be taken into consideration.
