Singlet fission (SF) is a down‐conversion photophysical process involving transforming a
high‐energy singlet state into two lower‐energy triplet excitons. It has attracted extensive …

X‐ray imaging technology is critical to numerous different walks of daily life, ranging from
medical radiography and security screening all the way to high‐energy physics. Although …

Transient absorption (TA) spectroscopy is an invaluable tool for determining the energetics
and dynamics of excited states. When pump intensities are sufficiently high, TA spectra …

We investigate dynamic signatures of the singlet fission (SF) process triggered by the
excitation of a molecular system to an upper singlet state SN (N> 1) and develop a …

Co‐deposited molecular heterostructures with statistical intermixing of the constituents are
attractive candidates to tune the optical and the transport properties, as well as the ability to …

Modifying the optical and electronic properties of crystalline organic thin films is of great
interest for improving the performance of modern organic semiconductor devices. Therein …

Singlet fission is a promising mechanism to boost the performance of solar cells. In order to
establish efficient singlet fission, it is essential to understand and control competing decay …

Singlet fission (SF) is a multielectron process in which one singlet exciton S converts into a
pair of triplet excitons T+ T. SF is widely studied as it may help overcome the Shockley …

Singlet exciton fission (SEF) is initiated by ultrafast internal conversion of a singlet exciton
into a correlated triplet pair (TT) 1. The “reaction coordinates” for ultrafast SEF even in …

The coherent distribution of an electronic excitation over multiple organic molecules in the
solid state, namely excited-state delocalization, plays an important role in photophysical …
