Sodium batteries (SBs) are a promising alternative to lithium-ion (LIBs) due the abundance, cost-effectiveness, and environmental sustainability of sodium. However, larger ionic radius Na+ leads challenges in electrode stability, limiting performance conventional inorganic cathode materials. Redox-active organic compounds, particularly π-conjugated quinones, have emerged as viable alternative, their tunable electrochemical properties, structural flexibility, enhanced compatibility with Na+....
Abstract Novel phenazine–fused triphenylene discotic liquid crystals (DLCs) tethered with alkanethiols and alkoxy chains are synthesized. The condensation of 4,5‐dibromobenzene‐1,2‐diamine triphenylene‐1,2‐diquinone core, followed by the reaction gives heterocyclic based DLCs. intermediate dibromo–substituted phenazine final alkanethiol substituted derivatives exhibit a wide range stable enantiotropic hexagonal columnar phase, which was characterised polarized optical microscopy (POM),...
The synthesis and characterisation of novel bent-core hockey-stick like liquid crystals from EDOT are reported. All the compounds exhibit an enantiotropic mesophase with a wide temperature range. These mesogens show good photophysical nonlinear optical properties.
A new paradigm of ionic liquid crystals exhibiting low-energy charge transfer bands is demonstrated. Thus, four series ion pairs 1,10-disubstituted derivatives the [closo-B10H10]2– anion and substituted pyridinium cations were prepared their thermal photophysical properties investigated. All form a smectic (SmA) phase with clearing temperatures above 200 °C intermolecular (CT) band in solid fluid states CH2Cl2 solutions. The CT maximum range 320–510 nm its position correlates difference...
Derivatives [ closo ‐B 10 H 8 ‐1,10‐(CN) 2 ] 2– and ‐1,10‐(OCHNMe ) ], efficiently obtained from ‐1,10‐(IPh) by nucleophilic substitution with CN – DMF, were envisioned as precursors to diacid ‐1,10‐(COOH) dihydroxy derivative ‐1,10‐(OH) , respectively. Attempts at hydrolysis or reduction of the dinitrile gave no reaction complex mixtures products. In contrast, DMF adduct was cleanly hydrolyzed diformate ‐1,10‐(OCHO) subsequently protonated ‐1,10‐(OH ]. The latter O‐acylated PhCOCl. Crystal...
