Multidimensional ultrafast spectroscopies are one of the premier tools to investigate
condensed phase dynamics of biological, chemical and functional nanomaterial systems. As …

The possibility of overcoming the Shockley–Queisser limit of organic solar cell (OSC)
efficiency by multiexciton generation through singlet exciton fission has recently attracted …

Ultrafast transient electronic absorption, one-and two-dimensional electronic-vibrational
spectroscopies were used to study the nonradiative relaxation dynamics of β-apo-8 …

In bacterial photosynthesis, the excitation energy transfer (EET) from carotenoids to
bacteriochlorophyll a has a significant impact on the overall efficiency of the primary …

A quenching mechanism mediated by the orange carotenoid protein (OCP) is one of the
ways cyanobacteria protect themselves against photooxidative stress. Here, we present a …

The singlet fission (SF) process is a promising route to overcome the Shockley and Quiesser
efficiency limit of organic solar cells and hence has attracted significant research interest in …

Fucoxanthin is an essential pigment for the highly efficient light-harvesting function of marine
algal photosynthesis. It exhibits excited state properties attributed to intramolecular charge …

Astaxanthin forms three types of aggregates in hydrated dimethyl sulfoxide (DMSO). In
DMSO/water ratio of 1: 1, a red-shifted J-aggregate with maximum at 570nm is generated …

Rhodopin, rhodopinal, and their glucoside derivatives are carotenoids that accumulate in
different amounts in the photosynthetic bacterium, Rhodoblastus (Rbl.) acidophilus strain …

Linear polyacenes and their derivatives are well-recognized organic semiconductors
because of their fascinating singlet fission (SF) property. However, higher polyacenes (eg …
