“…Fluorescence emission can be affected by a wide range of chemical or physical properties such as the length of the conjugated structure, the nature of substituted groups (electron donating or withdrawing power), intensity and wavelength of radiation, transparency or turbidity in colloidal solutions, size in the system colloids, concentration, and polarity of the surrounding environment (interaction between uorescent molecules with This journal is © The Royal Society of Chemistry 2023 solvent molecules or polar groups of the polymer matrix). 43 Fluorescent compounds are classied into organic dyes, 44 rare earth metal complexes, 45 quantum dots, 46 polymer dots, 47 and supramolecular structures, 48 and each of them has a potential application in the preparation of chemical sensors.…”

“…6,7 As an effective luminescent center, rare earth metals have been widely used in organic and inorganic luminescent materials. 8,9 The advantages of this method mainly include that the fluorescence performance of rare earth ions is generally more stable than that of quantum dots and less affected by the external environment. At the same time, the fluorescence lifetime of rare earth ions is usually longer than that of quantum dots, which gives them advantages in certain applications.…”

In order to expand the application of bio‐based polycarbonate in optical components, a series of PICC/ rare earth ion complex fluorescent composites were prepared by using PICC as macromolecular ligand and Eu3+ and Tb3+ as rare earth luminescence centers. The coordination system between rare earth ions and PICC was investigated by FTIR, DSC and TGA. At the same time, by adjusting the ratio of Eu3+ and Tb3+, the PICC/ rare earth ion composite with adjustable fluorescence color was obtained. At the same time, the thermal, mechanical and optical properties of a series of PICC/ rare earth ion fluorescent films with different ratios were tested. A transparent fluorescent composite material with excellent mechanical properties and tunable fluorescent colors has been prepared.This article is protected by copyright. All rights reserved.

This work presents a theoretical study on the geometries and intramolecular energy transfer (IET) process of Tb3+‐complexes based on the Ruhemman's purple (RP) as ligands. Density functional theory and its time‐dependent extension are performed to examine the coordination energies and excited states using the ωB97X‐D3/MWB54/def2‐TZVP/polarizable continuum model level of theory. The inclusion of solvent effect causes a blueshift in all excitation energies, which is crucial for a better description of the electronic situations of RP isomers and coordination compounds. The IET rates are assessed for 18 Tb‐RP different compounds, each one with 44 IET pathways, also, it is obtained that the main energy transfer channel comes from the singlet state, in complete agreement with previous experimental data. The energy transfer from the singlet state is mainly composed of the nonradiative absorptions 7F6→5G6 and 7F5→5G5, representing together 97% of the total IET rate. As far as it is known, this is the first time that the solvent effect is included in the IET rates calculation, registering a step toward the development of IET analysis without any experimental or phenomenological input data.
