Blends comprising organic semiconductors and inorganic quantum dots (QDs) are relevant for many optoelectronic applications devices. However, the individual components in organic-QD blends have a strong tendency to aggregate phase-separate during film processing, compromising both their structural electronic properties. Here, we demonstrate QD surface engineering approach using electronically active, highly soluble semiconductor ligands that matched host material achieve well-dispersed...
When considering the optimal molecular packing to realize charge multiplication in organic photovoltaic materials, subtle changes intermolecular transfer (CT) coupling can strongly modulate singlet fission. To understand why certain morphologies are more conducive by triplet pair (TT) formation, we measure diffraction-limited transient absorption (TA) response from four single-crystal functionalized derivatives of fluorinated anthradithiophene: diF R-ADT (R = TES, TSBS, TDMS, TBDMS). TES-ADT...
Halogen bonding is required in silylethyne-functionalized asymmetrical chromophores to yield crystal packing suitable for efficient transistors.
