A HSO-TiCT ion-gel is fabricated to prevent the restacking of TiCT for high-rate micro-supercapacitors. The ion-gel pillared by an electrolyte possesses an enlarged interlayer spacing facilitating ion transport. Furthermore, a bilayer structure is designed with dry TiCT for fast electron conduction. The bilayer TiCT film shows improved capacitance from 49% to 73% of the initial capacitance at a high scan rate of 200 mV s, along with excellent cycle stability. This study opens up a concise and efficient way for high-performance micro-supercapacitors.

Planarizable Push-Pull Probes: Overtwisted Flipper Mechanophores.

Planarizable push-pull fluorescent probes, also referred to as flipper probes, have been introduced as conceptually innovative mechanophores that report on forces in their local environment in lipid bilayer membranes. The best flipper probes respond to a change from liquid disordered to solid ordered membranes with a red shift in excitation of 50-90 nm. A simultaneous increase in fluorescence lifetime and negligible background fluorescence from the aqueous phase qualifies these fluorescent probes for meaningful imaging in live cells.

In the present study, we report the synthesis of gold (Au), silver (Ag), and gold-silver alloy (Au-Ag) nanoparticles (NPs) by seed-mediated method using gemini surfactant, containing diethyl ether spacer group as a stabilizer. As-synthesized NPs are found very much stable and have been characterized using UV-vis spectroscopy, X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and zeta potential techniques. The orientation of gemini surfactant molecules surrounding the metal NPs has been investigated exploiting twisted intramolecular charge transfer (TICT) fluorescence properties of a probe 4-(N,N-dimethylamino) cinnamaldehyde (DMACA).

Photoinduced electron transfer (ET) reactions between coumarin dyes and N,N-dimethylaniline have been investigated inside niosome, a nonionic innocuous polyethylene glycol (PEG)-based surfactant assembly using steady state and time-resolved fluorescence measurements. The location of coumarin dyes inside the bilayer headgroup region of niosome has been reported and it was verified by determination of the high distribution coefficient of all the dyes inside niosome compared to bulk water. Fluorescence anisotropy parameters of the dyes inside niosome are also in good correlation with the above inference about their location.
