Summary: This review discusses the recent advancements in hierarchical organization of molecular building blocks for improved photoconversion in organic solar cells. The self-sorted donor-on-donor/acceptor-on-acceptor arrangements have shown enhanced charge separation efficiency through ultrafast excited state dynamics. The controlled interface and electronic coupling between covalently linked donors and acceptors provide better charge carrier generation efficiency and offer new possibilities for functional supramolecular architectures.

Summary: Intramolecular through-space charge-transfer (TSCT) excited states are utilized for developing thermally activated delayed fluorescence (TADF) emitters, with a series of precisely controlled TSCT emitters designed through alignment optimization of donor and acceptor segments. By increasing intramolecular pi-pi interactions, radiative decay rate of the lowest singlet excited state (S-1) is progressively enhanced with suppression of nonradiative decay, leading to significantly improved photoluminescence quantum yields of up to 0.99 in doped thin films. A high-efficiency electroluminescence device achieves a maximum external quantum efficiency (EQE) of 23.96% and maintains >20% at a brightness of 1000 cd m(-2), highlighting the importance of conformation control for high-efficiency intramolecular exciplex emitters.

Summary: The photoinduced charge transfer mechanisms of two Donor-pi-Donor-pi-Acceptor conjugates are analyzed based on density functional theory calculations and visualization methods. The effects of the linkage between the two donors on the excitation characteristics are studied. The results show that the efficiency of superexchange charge transfer is affected by the change of bridge in one-photon absorption process, while the advantage of superexchange charge transfer is influenced by the linkage change in two-photon absorption process.

Summary: The use of intracellular-controlled photochemistry for tracking dynamic organelle processes is becoming more popular due to its broad applications. However, most molecular probes used for this purpose require toxic photosensitizers and complex bioanalytical protocols. In this study, we describe the synthesis and performance of two new subcellular probes (MitoT1 and MitoT2) that undergo photooxidation in damaged tissue of zebrafish, a model system for tissue regeneration studies. Through the use of high-resolution confocal microscopy and fluorescence spectroscopy, we were able to selectively track singlet oxygen activity by combining photoinduced interconversion at the homeostatic membrane viscosity. This continuous and real-time biosensing method provides a new approach for detecting endogenous singlet oxygen and viscosity status simultaneously.

Summary: This study presents a fabrication method for a low-cost and semitransparent three-layer graphene electrode. The electrode is made from an easily processable graphene derivative and the conductive polymer PH1000. Raman spectroscopy and theoretical calculations confirm the multilayer structure of the graphene derivative film, with an estimated 7 layers. Experimental measurements determine a thickness of approximately 5 nm for the film. The alternative three-layer graphene electrode exhibits a high transmittance of about 78% at 550 nm and a low electrical resistance of about 88 ohm/sq. These results show promising potential for the graphene derivative electrode in photovoltaic devices and other applications.

Summary: Two photovoltaic materials based on isoindigo (PFI) or diketopyrrolopyrrol (PFDPPT-A) and fluorene connected by thiophenes were designed and synthesized as electro-donors to obtain -(D-π-A) n polymers. Low-cost methodology was promoted by using the direct arylation (DA) reaction as a polymerization process for the synthesis of these photovoltaic materials. The molecular structure of the copolymers was established by IR, H 1 -NMR experiments, and determination of molecular weight. The electronic architecture of PFI and PFDPPT-A was estimated by theoretical study and confirmed by absorption spectroscopy and electrochemical measurements, confirming the intramolecular charge transfer. Evaluating the effect of n-bridge elongation on photovoltaic responses, a comparison of energy levels and optical features of polymers with similar structures was developed. The photovoltaic performance of PFI and PFDPPT-A was evaluated in organic solar cells (OSCs) using the BHJ approach and devices were fabricated under regular atmosphere conditions, showing improved photovoltaic character with the addition of thiophene ring, with PFI-based OSCs displaying a high Voc value of 1.05 V compared to previous isoindigo derivatives reports.

Summary: Lipid droplets (LDs), intracellular organelles found in various cell types, have been implicated in numerous diseases. However, current methods for monitoring LDs in vertebrate models are limited to static imaging using fluorescent dyes. In this study, we developed a fluorophore chemistry approach to enable dynamic monitoring of LDs in vivo using a Nernstian partitioning mechanism. We demonstrated the effectiveness of this method using a molecular probe in a zebrafish model of a human cardiovascular disease, providing a unique dual method for detecting disease evolution and recovery.
