Summary: Ambifunctional heterpentacenes with the heteroatom sequence SSNSS in the ladder-type backbone were used as either donor or nonfullerenic acceptor in solution-processed bulk-heterojunction solar cells. Different acceptor moieties and side chains were introduced. A dimeric heteroacene was synthesized and compared to its monomeric counterpart in terms of optoelectronic properties. The synthesis and characterization of systematically varied structural motifs provided insight into structure-property relationships.

Summary: Two squaraine dyes, USQ-O with oligo(ethylene oxide) (OE) chain and USQ-C with alkyl chain, were synthesized. The influence of the OE side chain on photovoltaic performances was investigated. USQ-C and USQ-O exhibited similar absorption spectra, energy levels, charge mobility, and molecular electrostatic potential (ESP) on the conjugated skeleton. However, USQ-O showed hypsochromic absorption band compared to that of USQ-C in the film, and a different distribution of positive and negative alternating ESP on the OE side chain. The different electrostatic interactions and hydrogen bonds among OE side chains affected the intermolecular interactions and the photophysical properties of the films.

Summary: Organic photovoltaic (OPV) devices often degrade with use in the field due to changes in active layer morphology. By combining different amounts of two Squaraines in a ternary blend with a fixed amount of fullerene acceptor, the film morphology can be varied, controlling the formation of H-aggregates. The co-existence of DHAs and CT-HAs is problematic, reducing power conversion efficiency by upwards of 15%.

Summary: Bulky N-substituents of 4-(hexyloxy) phenyl-substituted and 4-(hexylthio)phenyl-substituted triphenylamine were successfully introduced into double-anchored phenothiazine dyes as capping moieties for metal-free organic sensitizers in dye-sensitized solar cells. The N-substituent of 4-(hexyloxy)phenyl-substituted TPA provided the best steric matching and resulted in a compact dye packing and an integrated shelter layer on the TiO2 surface. The DSSC performance achieved with this modification was higher than that of the reference N719-based and HL5-based DSSCs.

Summary: Accurate quantification of the quantum yields (y) of both prompt fluorescence (PF) and delayed fluorescence (DF) is crucial for understanding the molecular design principles of thermally activated delayed fluorescence (TADF) luminogens. Existing TCSPC measurement systems cannot accurately measure y)PF of TADF materials due to a lack of valid data points in the faster decay region. In this study, we developed a modified TCSPC system using a low-cost time-to-digital converter (TDC) module, which can accurately determine the lifetime and y)PF/y)DF values of TADF fluorophores.

Summary: The horizontal orientation of the emissive transition dipole moment (TDM) of TADF emitters plays a crucial role in the efficiency improvement of OLEDs. By introducing functional groups containing weak hydrogen bonds into the host material, the horizontal orientation ratio (Theta) of the TDM can be significantly increased. The physical parameters of the dispersed emitter also have a strong relationship with the Theta values, with glass transition temperature being another key parameter.
