Herein we report the chemotactic behaviour of self-propelled droplets composed solely of the ionic liquid trihexyl(tetradecyl)phosphonium chloride ([P(6,6,6,14)][Cl]). These droplets spontaneously move along an aqueous-air boundary in the direction of chloride gradients to specific destinations due to asymmetric release of [P(6,6,6,14)](+) cationic surfactant from the droplet into the aqueous p...
Bacterial infections form part of the major causes mortality and morbidity around world more especially in developing under-developed countries. Cationic porphyrins have been reported to display better efficacy antimicrobial photodynamic therapy activity. The purpose this study was synthesise cationic porphyrins; (TAP) (TPyP) evaluate their pharmacokinetics metabolic interactions with DNA gyras...
Extensive investigations of asymmetric intermolecular cyclopropanation of terminal alkenes with diazoacetates catalyzed by ruthenium porphyrin [Ru(P*)(CO)(EtOH)] (1, H2P = 5,10,15,20-tetrakis[(1S,4R,5R,8S)-1,2,3,4,5,6,7,8-octahydro-1,4:5,8-dimethanoanthracene-9-yl]porphyrin) and the application of catalyst 1 to asymmetric intramolecular cyclopropanation of allylic or homoallylic diazoacetates a...
Despite advances achieved over the last decade, infections caused by multi-drug-resistant bacterial strains are increasingly becoming important societal issues that need to be addressed. New approaches have already been developed in order overcome this problem. Photodynamic antimicrobial chemotherapy (PACT) could provide an alternative fight infectious bacteria. Many studies highlighted value o...
A highly saddle-distorted dodecaphenylporphyrin dication (H4DPP2+) was revealed by X-ray crystallography to form positively charged porphyrin nanochannels which were 1 nm in diameter; chloride anion and redox-active hydroquinone could be incorporated in the channels.
A new supramolecular compound of adeninium bis(pyridine-2,6-dicarboxylate) Chromate(III) pyridine-2,6-dicarboxylic acid tetrahydrate (AdH+)[Cr(pydc)2](H2pydc).4H2O (1) (where Ad and H2pydc are adenine and pyridine-2,6-dicarboxylic acid, respectively) was synthesized via proton transfer method and its structure was determined using single crystal X-ray diffraction technique. This compound crysta...
