Trading lattice symmetry for long-lived triplets
Scientific Achievement
We use unit cell symmetry properties of supramolecular structures to boost their triplet formation efficiency to 60% from that of 1% in structural units.
Significance and Impact
This work reveals that lattice symmetry of supramolecular structures plays a critical role in triplet formation mechanism and efficiency.
- Fourier imaging technique used to determine the transition dipole orientations in the supramolecular structures.
- Monte Carlo simulation model developed to study charge transport dynamics.
- Transient absorption measurements used to verify the formation efficiency of triplet excitons.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials is one of the five DOE Nanoscale Science Research Centers, premier national user facilities for interdisciplinary research at the nanoscale supported by the DOE Office of Science. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, Sandia and Los Alamos National Laboratories.
