Summary: Exciton coupling in J-aggregates leads to shifted electronic transitions, lowering the excited state energy and allowing for emission in the near-infrared regime. The combination of superradiance and decreased nonradiative relaxation rate makes J-aggregates more emissive than monomeric counterparts, despite the red-shift in absorption. The reorganization energy suppression in J-aggregates enables increased emissivity in the NIR regime by circumventing the common belief of large nonradiative relaxation rates with lowered excited state energies.

Summary: In this study, a supramolecular coordination polymer (SCP) P was synthesized as an emissive material through a simple method. By further self-assembling into nanoaggregates, P showed enhanced emission and acted as a suitable host for adsorbing organic dyes. Using P as a donor, efficient light-harvesting materials were fabricated through a two-step energy transfer process, with a high FRET efficiency and antenna effect. These materials represent new examples of artificial LHSs based on nanoaggregates of an SCP.

Summary: Thermally activated delayed fluorescence (TADF) emitters have shown promising potential in organic light emitting diodes (OLEDs) due to their ability to harvest 100% excitons, but their broad emission spectra need to be addressed. Multiple-resonance TADF (MR-TADF) materials based on heteroatom doped polyaromatic hydrocarbons have achieved narrowband emission, but most current materials emit in the blue/green region, necessitating the development of new molecular designs to expand the color-gamut of MR-TADF emitters.

Summary: Thanks to tremendous efforts over the past 20 years, phosphorescent organic light-emitting diodes (PhOLEDs) have become a prevalent technology. Developing high-performance single-layer PhOLEDs (SL-PhOLEDs) is challenging due to the need to ensure efficient charge injection, transport, and recombination within the emissive layer. An analysis of different molecular design strategies for constructing high-efficiency hosts for SL-PhOLEDs has been conducted.

Summary: A precise control of nanoparticle size in the sub-nanometer regime is crucial for understanding nano-bio interactions and advancing nanomedicine. This study presents a simple Mn2+-guided centrifugation strategy to synthesize large-scale ultrasmall AuNPs with precise size gradient at the sub-nanometer regime. The researchers discovered that [Mn(OH)](+) nanoparticles, particularly Mn-0@[Mn(OH)](+), can selectively interact with larger AuNPs to form aggregates, leading to the efficient synthesis of water-soluble atomically precise Au-25 within a short time. Moreover, the study demonstrates the significant impact of sub-nanometer size differences on non-specific phagocytosis, elimination rate, and nanotoxicology of AuNPs in macrophages.
