Isopinocampheyl-based C-BODIPYs: a model strategy to construct cost-effective boron-chelate emitters of circularly polarized light

Efficient circularly polarized luminescence (CPL) brightness from 4,4-diisopinocampheylBODIPY is detected for the first time. This finding demonstrates the workability of a new design, based on using chiral-pool derived chloro(diisopinocampheyl)borane, to construct low-cost CPL-active boron chelates, paving the way towards the development of sought cheaper organic emitters of circularly polarized light.
