Enantioselective C–H functionalization relies on 4d and 5d metals, but with their depletion, sustainable alternatives using 3d metals are crucial.

The divergent synthesis of natural products enables efficiency and economy in chemical synthesis, making more molecules with a single route at the beginning and divergence at the late stage.

This article delineates the advantages of fluorescence correlation spectroscopy and fluorescence lifetime imaging microscopy for elucidating the spontaneous and stimuli-responsive morphological transformation of luminescent self-assembled structures.

This article highlights the recent advances on newer technologies and important methodologies directed to (E)-olefins from alkynes.

The effect of reactant alignment on the angular distributions of scattered products in atom-molecule scattering.

In this feature article, we have outlined a comprehensive review on construction and chemical behaviour of heteroditopic wheels based new-generation interlocked molecules and their applications in different directions of contemporary research area.

meta-fluorophores hold the promise to create an uncharted ocean of hitherto unachieved opportunities.

This Feature Article describes recent progress in the area of chain-folding regulated self-assembly of segmented polymers and direct correlation between secondary structure of the polymers with their functional properties.

Current developments and future prospects of CNM-based polymeric membranes for enantiomeric separation, wastewater treatment, gas separation, and biomolecule separation are highlighted in this feature article.

Examples of C–H modification of natural products as a minimalist enabling tactic to improve pharmacophysical properties are overviewed.

Two π-extended nonplanar cobalt porphyrins embedded MWCNTs manifested efficient electrocatalysts for selective ORR under ambient conditions with excellent methanol tolerance and high stability due to effective π–π interactions.

A novel, biodegradable substrate based, and cost-effective flexible electrochemical sensor was developed for the selective and sensitive detection of dopamine, which can be utilised as a disposable electrode for point-of-care diagnostic applications.

Photopolymerization of aggregated monomers is introduced for modulating water wettability. A stable aqueous dispersion of monomer aggregates was achieved by transferring the dissolved monomer from a ‘good-solvent’ into a ‘bad-solvent’.

Metal-free hydride stabilized boron nanosheets were synthesized in an aqueous medium in mg scale and their suitability as an anode material for Li-ion batteries in half-cell mode was demonstrated.

Unsymmetrical ketones have been efficiently synthesized adopting a new strategy via cross-coupling of α,β-unsaturated carboxylic acids and aryldiazonium salts under dual photoredox/metal catalysis.

An energy efficient and durable solution for high CO₂ emission has been introduced via the development of an ionic liquid and amine channelized mixed matrix membrane with high CO₂ permeance and CO₂/N₂ selectivity.

We have developed a synthesis of 1-3 and 1-1 disaccharides from 2-benzoyl glycal and anomeric thiol and/or hydroxy sugar acceptors under mild conditions at room temperature.

A non-traditional, divergent approach to the synthesis of pyrrole carboxamides from pyrrole carboxaldehydes and formamides or amines via oxidative amination in the presence of TBHP and a catalytic amount of TBAI is reported.

A NIR emissive helical bis(naphthobipyrrolyl)methene-derived open chain hexapyrrolic BODIPY has been synthesized with a fluorescence quantum yield up to 0.27.

A rhodium-catalyzed carboamination of olefin with the retention of double bond has been demonstrated. A deacylative carboamination of the maleimide has been achieved. In addition to carboamination, we have also disclosed ortho C–H olefination of phenoxyacetamides.

The reactions of 6-SIDipp·AlH₃ (1) with 5-IDipp or 5-IDipp·AlH₃ with 6-SIDipp resulted in the ring expansion of six-membered NHC, while the five-membered NHC remained intact.
