The
development of small organic CPL-active molecules with large
luminescent dissymmetry factors is highly demanded due to their promising
applications in chiroptical devices and sensors. This work describes
the design and synthesis of a new family of CPL-active BF2 complexes, (Rp)/(Sp)-3a–3e, which were constructed
by fusing a N̂O-chelated BF2 complex with [2.2]paracyclophane.
These complexes display aggregation-amplified CPL with moderate dissymmetry
factors values and moderate quantum yields both in solution and in
the solid state. In addition, these photophysical properties were
rationalized via X-ray diffraction and TD-DFT calculations.
