Aggregates of conjugated polymers exhibit two classes of fundamental electronic
interactions: those occurring within a given chain and those occurring between chains. The …

A new model for analyzing the photophysics of polymer aggregates is introduced taking into
account exciton motion along a polymer chain and across polymer chains. Excitonic …

The photoluminescence (PL) spectral line shape of regioregular poly (3-hexylthiophene)
thin films is analyzed using a model which treats the polymer π-stacks as H-aggregates with …

A series of donor− spacer− acceptor triads has been synthesized and fully characterized.
Both donor and acceptor units are built from boron dipyrromethene (BODIPY) dyes but they …

The properties of polymeric nanofibers can be tailored and enhanced by properly managing
the structure of the polymer molecules at the nanoscale. Although electrospun polymer …

A theory describing vibronic coupling in direct band gap, one-dimensional semiconductors
is developed to account for the photophysical properties of isolated, defect-free conjugated …

We show that the exciton transport and decay processes in two poly (p-phenylene
vinylene)(PPV) based semiconducting polymers exhibit distinct temperature dependence …

Semiconductor polymers are the foundation of organic electronics due to their remarkable
optical features, ability to form a thin film, and low cost compared to silicon. However, some …

Steady-state and time-resolved photoluminescence have been used to investigate the
photophysical properties of the poly (para-phenylene vinylene) copolymer Super Yellow …

Our extensive study based on optoelectronic and electric measurements (which consisted
of: UV–Vis absorption, photoluminescence, surface photovoltage measurement, charge …
