Structural and functional heterogeneity is a consequence of the weak noncovalent
interactions that direct the formation of organic materials from solution precursors. While …

Over the past decade, the proliferation of pulsed laser sources with high repetition rates has
facilitated a merger of ultrafast time-resolved spectroscopy with imaging microscopy. In …

Singlet fission (SF) materials used in light-harvesting devices must not only efficiently
produce spin-triplet excitons but also transport them to an energy acceptor. N, N′-Bis (2 …

Triplet–triplet annihilation photon upconversion (TTA-UC) is a process able to repackage
two low-frequency photons into light of higher energy. This transformation is typically …

Photon upconversion in the solid state has the potential to improve existing solar and
infrared imaging technologies due to its achievable efficiency at low power thresholds …

A detailed understanding of defects and ordering within technologically relevant materials is
key for future commercial implementation. Here, we highlight recent work by Volek et al …

Laser desorption mass spectrometry was employed to study rubrene using three different
sample preparation methods. Pressed-pellet and films drop-cast from solution were …

Photon upconversion within the solid state has the potential to improve existing solar and
