Summary: The novel supramolecular host-guest systems exhibited interesting photoluminescence properties in DMF/H2O solutions, including bifluorophoric behavior after aluminum detection. Notably, Forster resonance energy transfer processes occurred between blue-emissive TPE donors and green-emissive fluorescein acceptors, resulting in strong green emissions. These systems showed high sensitivities and selectivities toward aluminum ions with effective FRET processes, making them promising for aluminum detection applications.

Summary: A novel series of dendritic compounds with peripheral pyrene groups and a porphyrin core were synthesized and characterized in this study. Metallation with Zn(II) and Mg(II) resulted in red shifts in the Soret absorption band and blue shifts in the emission band for the dendritic porphyrins, with all compounds exhibiting high energy transfer efficiency.

Summary: This study synthesized TPE-anchored cationic surfactants with AIE characteristics, and for the first time quantitatively demonstrated that CRET efficiency is inversely proportional to the sixth power of distance between luminol donors and TPE acceptors, revealing that CRET follows Forster resonance theory.

Summary: Our study developed the first intermolecular DRET pair for specific sensing of nucleic acid sequences, demonstrating significantly improved fluorescence response by combining DFK with Cy5-labeled complementary sequences. The results indicate that DRET has low background noise when detecting sequences of interest.

Summary: Donor-bridge-acceptor systems based on BODIPY show potential for bio-imaging and sensing applications, with their photophysical behavior depending on solvent polarity. Factors such as donor-acceptor distance and restricted rotational motion play key roles in tuning the excited state photophysics.

Summary: This study demonstrates a transition from incoherent to coherent electronic energy transfer in donor-acceptor model systems by precisely controlling the separations. Through scanning tunnelling microscopy induced luminescence, two new emission peaks were observed with decreasing intermolecular distance. The spatially resolved spectroscopic images of the redshifted emission reveal a delocalized nature of the excitonic state over the whole heterodimer, suggesting a coherent wave-like transfer of the excitons.

Summary: Enhanced delocalization is beneficial for absorbing molecules in organic solar cells, and polaritons offer exceptional delocalization that can improve the efficiency of bilayer organic photovoltaics by aiding in exciton delivery to the donor-acceptor interface. The decay of polaritons in bilayer cavities shows an additional pathway through charge transfer, indicating that the charge transfer from the polariton is fast enough to outcompete decay to the ground state.

Summary: Quantitative fluorescence quenching is a common method used to study chemical reactions. The Stern-Volmer equation is often used for analysis, but it is not suitable for Forster Resonance Energy Transfer (FRET) as the primary quenching mechanism. This study demonstrates that the nonlinear distance dependence of FRET leads to significant deviations from the standard Stern-Volmer quenching curves. The distribution of interparticle distances and diffusion play important roles in fluorescence quenching, especially in the shortwave infrared region.

Summary: Two new dyes were synthesized with an aromatic amine donor and dansyl acceptor connected by Diels-Alder dynamic covalent bonds, allowing switchable fluorescence resonance energy transfer. Single crystal X-ray diffraction revealed the longer and weaker nature of Diels-Alder bonds compared to normal single bonds. The dynamic covalent properties enable mutual conversion of the dyes through maleimide exchanges to construct a new system with higher energy transfer efficiency.

Summary: This study investigates the photophysical properties and aggregation behavior of asymmetric perylene and naphthalene diimides grafted to the edge of layered silicate Laponite. FRET was observed from naphthalene diimide- to perylene diimide-functionalized Laponite, with significantly enhanced FRET achieved by pillaring Laponite with a cationic surfactant. The results demonstrate the ability to tune donor-acceptor interactions and energy transfer processes in inorganic-organic hybrid materials.

Summary: The study showed that the aromatic donor-acceptor interactions between pyrene and pyromellitic diimide derivatives were stronger in siloxane solvents compared to aliphatic solvents due to the poor solubility of the aromatics in siloxanes.

Summary: Molecular materials with pi-conjugated donor-acceptor and acceptor-donor-acceptor structures have versatile applications in organic photovoltaic materials, organic light-emitting diodes, and biological imaging agents. Boron-containing compounds with unique optoelectronic and redox properties are synthesized using Stille cross-coupling chemistry. The compounds exhibit reversible redox waves, solid-state emission, and aggregation-induced emission. The optical band gaps determined from experiments and density functional theory calculations support the rationalization of the observed optoelectronic properties. This study provides a foundation for incorporating these boron-containing compounds into applications that require fine-tuning of band gaps.
