Summary: In this study, a new type of spherical nucleic acids (SNAs) was developed by using fluorescent pi-conjugated polymers (FCPs) as light-harvesting antennas to enhance signal transduction in nucleic acid detection. The hydrophobicity of the graft copolymer was adjusted to control the size and light-harvesting capability of the FCP-SNAs. The optimized FCP-SNA showed a 37-fold signal amplification effect and a limit of detection as low as 1.7 pM in microRNA detection. This method was successfully applied for amplified in situ nucleic acid detection and imaging at the single-cell level.

Summary: In this study, a cationic cyano-substituted p-phenylenevinylene derivative (PPTA) was synthesized and used to form supramolecular assemblies with anionic guar gum (GP5A) through electrostatic interaction. A polyelectrolyte-based artificial light harvesting system (LHS) was constructed using a fluorescent dye (SR101) as an energy acceptor. The energy harvested by the acceptor was utilized in a cross dehydrogenation coupling (CDC) reaction in the aqueous phase, achieving a yield of up to 87%. The general applicability of polyelectrolyte materials in constructing artificial LHSs was demonstrated using three other polyelectrolyte materials (RSS, CMC, and PAAS), which also achieved high yields in the CDC reaction. This work not only presents a new method for constructing LHSs using polyelectrolyte materials, but also explores the potential application of harvested energy in LHSs for aqueous photocatalysis.

Summary: A controllable protein nanostructures-based On/Off switchable artificial light-harvesting system with sequential multistep energy transfer and photocatalysis was reported, mimicking the natural system in structure and function. Single-layered protein nanosheets were constructed with an ordered arrangement of pigments, and fluorescent chromophores were distributed on the nanosheets via electrostatic interactions. The system achieved sequential energy transfer and high-efficiency photocatalysis. The catalytic process could be regulated by an On/Off switch.

Summary: We develop a method to simulate the dynamics of light harvesting systems, considering non-Markovian coupling and multi-photon excitation. We find that under weak field excitation, coherent state input and Fock state input lead to equal density matrices in the excited manifold, but only coherent state input creates off-diagonal coherence. We also analyze the absorption probability and derive expressions for short and long pulses, as well as study the difference between collective vs independent emission.

Summary: In this study, we designed and constructed two artificial light-harvesting systems based on the supramolecular self-assembly of acylhydrazone functionalized quinoline (L), Al3+, and fluorescent dyes. The L-Al3+ supramolecular assembly significantly improved aggregation-induced emission enhancement and served as a donor for the light-harvesting systems. Acridine yellow and acridine orange were found to be efficient acceptors for the energy transfer process.

Summary: We investigated the energy transfer mechanism in the phycobilisomes (PBSs) of the thermophilic cyanobacterium Thermosynechococcus vulcanus NIES 2134 (T. 2134) using cryo-EM models resolved at near-atomic resolution and sub-picosecond time-resolved fluorescence spectroscopy. We identified four time components and revealed the energy transfer channels and rates in the PBSs. This study contributes to our understanding of energy transfer mechanisms in PBSs.

Summary: The study focuses on the immobilization of a molecular triad (NDADI-P-Ru-TEMPO) on a mesoporous conducting indium tin oxide electrode for selective oxidation of para-methoxybenzyl alcohol. The reaction under light irradiation shows high TON and approximately 80% faradaic efficiency. Additionally, the photophysical study indicates that photoinduced electron transfer is slow and must compete with direct electron injection.

Summary: The structure of a decanuclear dendrimer based on Ru(II) polypyridine subunits, suitable for artificial photosynthesis as a light-harvesting species, has been investigated through computer modeling. Molecular dynamics and quantum mechanics simulations were used to study the stability of possible isomers of each monomer, revealing a prevalence of MER isomerism in the central core. Additionally, the self-aggregation of the dendrimer and the distribution of counterions around the complexes were investigated using Molecular Dynamics in both implicit and explicit acetonitrile solution, suggesting a self-aggregation mechanism for the dendrimers.

Summary: The study investigated a decanuclear photo- and redox-active dendrimer based on Ru(II) polypyridine subunits using computer modelling. It was found that the stability of the dendrimer is governed by the steric constrains originated by the multimetallic assembly rather than the stability of the individual monomers. Additionally, molecular dynamics analysis showed a self-aggregation mechanism of Ru10. The results provide new insights for the design and development of light-harvesting multicomponent species for artificial photosynthesis.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
