Flexible Full-Inorganic Ultrathin Films with Stable Circularly Polarized Luminescence Covering the Visible to Near-Infrared Region
Chemphyschem. 2024 Mar 20:e202400138. doi: 10.1002/cphc.202400138. Online ahead of print.ABSTRACTCircularly polarized luminescence (CPL) materials hold significant value in various fields, including information storage, secure communication, three-dimensional displays, biological detection, and optoelectronic devices. Using the Langmuir-Schaeffer (LS) assembly technique, we successfully construct a series of large-area flexible optical ultrathin films. Impressively, the inorganic assembled ultrathin films exhibit excellent CPL optical activity covering the visible to near-infrared (NIR) region, with the luminescence asymme...

Modified Donor End Caps for Binary-to-Ternary WORM Memory Conversion in N-Heteroaromatic Systems
Chemphyschem. 2024 Mar 20:e202400062. doi: 10.1002/cphc.202400062. Online ahead of print.ABSTRACTA series of novel A-π-D type organic small molecules have been designed, synthesized, and demonstrated for non-volatile resistive switching WORM memory application. The electron-deficient phenazine and quinoxaline units were coupled with various functionalized triphenylamine end caps to explore the structure-property correlations. The photophysical investigations displayed considerable intramolecular charge transfer, and the electrochemical analysis revealed an optimum band gap of 2.44 to 2.83 eV. These factors and the thin fi...

A Rotational Study of 2-tert-Butylphenol and Its 1:1 Argon Complex
Chemphyschem. 2024 Mar 19:e202400089. doi: 10.1002/cphc.202400089. Online ahead of print.ABSTRACTThe chirped-pulse Fourier Transform microwave spectrum of 2-tert-butylphenol, an industrial intermediate for the production of antioxidants, has been investigated in the 2-8 GHz frequency range. The spectral analysis has allowed obtaining precise structural information on the most stable conformer and its complex with argon. The conformation of the monomer reveals that the hydroxyl group is coplanar with the ring but points in the opposite direction to the tert-butyl group, reducing steric interactions. In the terbutyl group on...

Concentration-gradient structural LiFe0.5Mn0.5PO4/C prepared via co-precipitation reaction for advanced lithium-ion batteries
Chemphyschem. 2024 Mar 17:e202300930. doi: 10.1002/cphc.202300930. Online ahead of print.ABSTRACTThe intrinsically low electronic conductivity and slow ion diffusion kinetics limit further development of olivine LiFexMn1-xPO4 cathode materials. In this paper, with the aim of effectively improving the performance of such materials and alleviating the Jahn-Taller effect of Mn3+ ion, a bimetallic oxalate precursor with gradient distribution of elemental concentration followed with a efficient process is applied to synthesize LiFe0.5Mn0.5PO4 nanocomposite. The results shown that with certain structural modulation of the precur...

Density functional theory calculations on fluorescence-enhanced mechanisms of the optical sensor for zinc ions, ADPA
Chemphyschem. 2024 Mar 18:e202400140. doi: 10.1002/cphc.202400140. Online ahead of print.ABSTRACTN-(9-anthracenylmethyl)-N-(2-pyridinylmethyl)-2-pyridinemethanamine (ADPA) as a specific ion sensor for Zn2+ has been widely applied. Although the photo-induced electron transfer (PET) mechanism was proposed previously, its fluorescence-enhanced effect still remains somewhat ambiguous, according to unknown influences of non-radiative energy decay pathways, such as intersystem crossing and internal conversion. Herein, a thorough study using density functional theory has been performed for low-lying electronic states of the ADPA ...
