We analyze correlated-triplet-pair (TT) singlet-fission intermediates toward two-triplet
separation (T... T) using spin-state-averaged density matrix renormalization group electronic …

A first-principles description of the primary photochemical processes that drive
photosynthesis and sustain life on our planet remains one of the grand challenges of …

Summary The S 1 (2 1 A g–) state is an optically dark state of natural and synthetic pi-
conjugated materials that plays a role in optoelectronic processes, such as energy …

Singlet exciton fission is the spin-allowed generation of two triplet electronic excited states
from a singlet state. Intramolecular singlet fission has been suggested to occur on individual …

The peridinin-chlorophyll a-protein is a light-harvesting complex found in dinoflagellates,
which has an unusually high fraction of carotenoids. The carotenoids are directly involved in …

Observations of low-lying dark states in several photosynthetic complexes challenge our
understanding of the mechanisms behind their efficient energy transfer processes …

The key components of the far-red-light forms of PSI and PSII are chlorophylls d and f which
are able to absorb this light contrary to chlorophyll a. The aim of this work is to reveal the …

In this thesis, we describe our investigations into the mechanism of singlet exciton fission,
examining the effects of morphology, aromaticity, and photoluminescence yield on the …
