Tetraphenylporphyrin (H 2 TPP) and zinc tetraphenylporphyrin (ZnTPP) are widely used
benchmark molecules in diverse photochemical studies given facile synthetic access, rich …

Ultrafast photochemical reactions in liquids occur on similar or shorter time scales compared
to the equilibration of the optically populated excited state. This equilibration involves the …

The femtosecond-resolved evolution of the emission spectrum of the important conjugated
polymer poly (3-hexylthiophene)(P3HT) is presented. Detailed fluorescence up-conversion …

Femtosecond spectroscopic studies of zinc tetraphenylporphyrin (ZnTPP) in benzene and
dichloromethane are reported, combining both fluorescence up-conversion and transient …

The nature and time evolution of the primary excitations in the pristine conjugated polymer,
PCDTBT, are investigated by femtosecond-resolved fluorescence up-conversion …

Polymerization reactions initiated by ultraviolet light are ubiquitous in scores of industrial
applications but would markedly benefit from visible-light activation to overcome stability …

Photoinduced symmetry-breaking charge separation (SB-CS) processes offer the possibility
of harvesting solar energy by electron transfer between identical molecules. Here, we …

The excited-state dynamics of the DNA bisintercalator YOYO-1 and of two derivatives has
been investigated using ultrafast fluorescence up-conversion and time-correlated single …

In this study, we describe synthesis, characterization, and zipper assembly of yellow p-
oligophenyl naphthalenediimide (POP-NDI) donor− acceptor hybrids. Moreover, we …

The influence of solute− solvent interactions on the vibrational energy relaxation dynamics
of perylene and substituted perylenes in the first singlet excited-state upon excitation with …
