Luminescent small, all‐organic molecules are of tremendous interest in materials and life
science applications. Nevertheless, targeted design requires a basic understanding of the …

The electronic excited states of molecular aggregates and their photophysical signatures
have long fascinated spectroscopists and theoreticians alike since the advent of Frenkel …

All-polymer solar cells (all-PSCs) based on polymerized small molecular acceptors (PSMAs)
have made significant progress recently. Here, we synthesize two A-DA'DA small molecule …

Mixed conductors—materials that can efficiently conduct both ionic and electronic species—
are an important class of functional solids. Here we demonstrate an organic nanocomposite …

Organic (opto) electronic materials have received considerable attention due to their
applications in thin-film-transistors, light-emitting diodes, solar cells, sensors, photorefractive …

Conjugated polymer chains have many degrees of conformational freedom and interact
weakly with each other, resulting in complex microstructures in the solid state …

The optoelectronic properties of macromolecular semiconductors depend fundamentally on
their solid-state microstructure. For example, the molecular-weight distribution influences …

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

Organic semiconductors offer the potential for large-area deposition on substrates of flexible
or unique form factors and can be deposited at ambient conditions at low cost. They can be …

The specific optical absorption of an organic semiconductor is critical to the performance of
organic optoelectronic devices. For example, higher light-harvesting efficiency can lead to …
