Here two AB type corrole has been synthesized and solubilized in water via pluronic micellar system by avoiding the utmost mandatory multistep non-environment friendly strategies for bringing hydrophobic non-ionic corroles in aqueous medium. Both the corroles were extremely insoluble in water as no absorption spectra of corrole was available in water. However, corrole 2 in the aqueous solution of F127 exhibit characteristic Soret and Q bands due to efficient solubilization of corrole in F127, the micelles formed by block copolymer act as a "cargo hold" for the corrole molecules. Intense emission spectra were observed for both the corroles in the aqueous solution of F127. We further observed that fluorescence properties of corrole-F127 micelle systems are quenched in presence of graphene oxide (GO) without change in the wavelength or shape of the emission band. The possibility of a dynamic quenching is probed more quantitatively by recording the emission decay profiles of corrole-F127-GO system. This quenching of fluorescence intensity of graphene oxide dispersed corrole-F127 micellar system was partially re-established in the presence of bioanalytes such as dopamine, ascorbic acid. Therefore, the present work has a future potential application for analyzing the interaction with different bioanalytes in biological systems using corrole-GO composite.

Article Synopsis
- The study focused on synthesizing 5,15-bis(perfluorophenyl)-10-(4-carboxyphenyl) corrole and its metal complexes with Co(III), Mn(III), and Cu(III) to investigate their ability to catalyze the hydrogen evolution reaction (HER).
- Various proton sources, including AcOH, trifluoroacetic acid, and TsOH, were tested in dimethylformamide to analyze the pathways (EECC, EECEC, EEECEC) for HER based on acidity and concentration.
- Among the complexes, the Co corrole exhibited the highest efficiency with a turnover frequency of 201 s, showing the catalytic activity ranking as Co > Cu > Mn in

Article Synopsis
- Hydrazine is highly toxic and poses a risk to the environment and living organisms, making it crucial to monitor its levels for human health.
- A new fluorescent probe called PC-N H has been developed, which effectively detects hydrazine with great specificity, a low limit of detection (88 nM), and functions across a wide pH range (6-12).
- The probe demonstrates a significant increase in red fluorescence upon interacting with hydrazine and has been successfully implemented for visual testing in water samples and imaging in biological models like HeLa cells and zebrafish.

Two new -substituted oxido-molybdenum corroles were synthesized and characterized by various spectroscopic techniques. In the thermogram, MoO[TTC] () exhibited excellent thermal stability up to 491 °C while MoO[TNPC] () exhibited good stability up to 318 °C. The oxidation states of the molybdenum(V) were verified by electron paramagnetic resonance (EPR) spectroscopy and exhibited an axial compression with configuration.

The increase in the antibiotic resistance of bacteria is a serious threat to public health. Photodynamic inactivation (PDI) of micro-organisms is a reliable antimicrobial therapy to treat a broad spectrum of complex infections. The development of new photosensitizers with suitable properties is a key factor to consider in the optimization of this therapy.
