Summary: The present study investigates the site-selective symmetries in Eu3+-doped KY3F10 with different crystal phases. Time-resolved fluorescence line-narrowing (TRFLN) is employed to study the luminescent response of the dopant in samples containing single delta-phase, single alpha-phase, and a mixture of both delta and alpha. A new method is developed to obtain nanospheres of the delta-phase, which is simple, time-saving, and high-yield. Spectral analysis confirms the expected site symmetries in both crystal phases, and significantly distorted Eu3+ ions are found on the surface of the nanoparticles, indicating common behavior in glassy systems. The study reveals the potential of the unexplored delta-phase, with the site-selective emission of Eu3+-doped delta-phase being up to 20 times more intense than that of the alpha-phase.

Summary: A simple, green, and solvent-free pyrolysis method for the preparation of starch-based carbon dots (CDs) was developed. The CDs prepared at 300 degrees C exhibited a highest quantum yield of 21.0%, which was mainly due to the high degree of graphitisation of the CDs. The CDs were selective for the detection of Ru3+ ion solutions.

Summary: The novel BODIPY fluorescent probe BDBH was developed for high selectivity and sensitivity detection of fluoride, with an 80-fold increase in emission intensity upon addition of TBAF. The interaction between BDBH and fluoride involved hydrogen bonding formation at low concentration and deprotonation of NH group at increasing concentration, leading to enhanced planarity and conjugation and resulting in strong fluorescence emission at 613 nm. Confocal fluorescence images of BDBH-incubated HeLa cells confirmed its potential application as an off-on sensor for monitoring fluoride in living cells.

Summary: Both pillar[n]arenes (P[n]As) and [n]cycloparaphenylenes ([n]CPPs) have been synthesized and integrated into bismacrocycles [n]CPP-P[5]A. The bismacrocycles exhibit higher photoluminescence quantum yield (phi(F)) compared to the corresponding [n]CPPs. Chiral enantiomers (pR)/(pS)-[8]CPP-P[5]A with circularly polarized luminescence (g(lum)approximate to 0.02) were successfully isolated, and the bismacrocycles showed high affinity and specificity towards pyridinium salts and fullerene derivatives. Transient absorption studies revealed photo-induced electron transfer in [10]CPP-P[5]A superset of C-60 complex. The results suggest the potential applications of [n]CPP-P[5]A in CPL-active materials, multiple guest recognition, and supramolecular polymer preparation.

Summary: In this study, we report on the self-assembly behaviors of four pairs of enantiomeric platinum(II) complexes with minor structural variations. The different non-covalent interactions between the complexes result in the formation of various well-defined nanostructures, including nanorings, nanotwists, dendritic twists, and microbelts. Two pairs of enantiomers show amplified effects for circular dichroism (CD) and circularly polarized luminescence (CPL) in their nanoassemblies. The self-assembly process is governed by Pt...Pt/7C-7C stacking, solvophobic interactions, and electrostatic repulsion.
