Title
Circularly polarized luminescence from helically chiral N,N,O,O-Boron-chelated dipyrromethenes
Author
Abstract
Helically chiral N,N,O,O-boron chelated dipyrromethenes showed solution-phase circularly polarized luminescence (CPL) in the red region of the visible spectrum (lambda(em)(max) from 621 to 663 nm). The parent dipyrromethene is desymmetrised through O chelation of boron by the 3,5-ortho-phenolic substituents, inducing a helical chirality in the fluorophore. The combination of high luminescence dissymmetry factors (vertical bar g(lum)vertical bar up to 4.7 x 10(-3)) and fluorescence quantum yields (Phi(F) up to 0.73) gave exceptionally efficient circularly polarized red emission from these simple small organic fluorophores, enabling future application in CPL-based bioimaging.
