Self-assembly induced tunable multiple fluorescence output from a white light-emitting functionalized single π-conjugated molecule and implication in VOC sensing applications

Abstract

Fluorescent nanostructures obtained from small organic molecules or generated from supramolecular assembly of various functional π- conjugated molecules have concerned significant importance due to their potential applications in colour tunable...

First-Principles Density Functional Theory Calculations on the Potential of Sc2CO2 MXene Nanosheets as a Dual-Mode Sensor for Detection of Volatile Organic Compounds in Exhaled Human Breath

“…In the case of sensors, DFT investigations help to understand host–guest interactions via the electronic properties analysis. In most of our previous studies, both experimental and theoretical results have agreed with each other. ,,,− Therefore, we believe that our results obtained through single VOC interaction with the ideal Sc 2 CO 2 system will assist the experimentalist in fine-tuning the sensor operation. Moreover, a recent report has highlighted that the formation enthalpy of 2D Sc 2 C (−0.144 eV/atom) suggests that it is a stable material and it can be synthesized .…”

Design and development of imidazo[4,5-f] [1,10] phenanthroline-Zn(ii) based fluorescent probes for specific recognition of ATP with tunable optical responses and probing the enzymatic hydrolysis of ATP by alkaline phosphatase

“…). 72,80 While the absorption band at a shorter wavelength (at 283 nm) is presumably from the π-conjugated system based π–π* transition. 81 Similarly, (P2) 2 Zn exhibited two absorption peaks at 279 and 297 nm (Fig.…”

“…In the last three decades, p-conjugated aromatic organic compounds have been extensively employed as a major component in electronic, optical, and sensor devices. [70][71][72] Different derivatives of imidazo [4,5-f] [1,10] phenanthroline, in particular 2-substituted ones, have been used as photoactive materials, luminescent sensors, and OLED components for nonlinear optical applications. 73,74 These derivatives have also found potential application in bio-medical research due to their cell penetrating ability and capability of intercalating into DNA and influencing their functional properties.…”

Recent advances in aggregation-induced emission (AIE)-based chemosensors for the detection of organic small molecules

“…For the detection of simple alcohols, Das and Surya et al designed two novel isomeric Schiff bases ( C1a and C1b ) which self-assemble into various super-structures in solvents with different polarities, revealing different colours of fluorescence from blue to green, yellow, and white. 225 Using a scanning Kelvin probe, the surface photovoltage measurements of C1a and C1b films can be obtained to detect 1-hexanol, which is selectively adsorbed onto the film surfaces via hydrogen bonding interactions, with response times of 250 and 360 s, respectively. Similarly, Han and Liao et al prepared donor–acceptor type Schiff base ( C2 ) which coated-paper probes reveal an enhancement of cyan-blue/blue fluorescence on fumigation with methanol and ethanol.…”
