Work at the Langmuir-Blodgett trough

Second year PhD student Bruno D’Agostino visited the University of Southampton last week as part of a collaboration with Dr Jon Kitchen on lanthanide-based Langmuir-Blodgett films. He also attended the day-long 2017 Southampton Supramolecular Symposium on Friday, which was organised by the Kitchen and Goldup groups in Southampton.

New paper in Organic Letters on anion mediated synthesis of 3-amino-[1,2,4]-triazolo pyridines from our group

Many congratulations to present and former members of our group Komala, Anna, Devis, Jon, Miguel and Salvador for their recent publication, Supramolecular Anion Recognition Mediates One-Pot Synthesis of 3-Amino-[1,2,4]-triazolo Pyridines from Thiosemicarbazides, in Organic Letters!. This work was done through a collaboration of Prof. Gunnlaugsson and Prof. Eoin Scanlan and showed how supramolecular interactions with F (as tetrabutylammonium fluoride, TBAF) of a series of thiosemicarbazides could lead to the formation of 3-amino-[1,2,4]-triazolo pyridines. The synthesis of these heterocycles was obtained in a one-pot reaction from variously substituted hydrazine pyridine and isothiocyanates in the presence of TBAF.

Three new papers accepted for publication from the group

Many congratulations to Bjørn C. Poulsen, Sandra Estalayo-Adrián, Salvador Blasco and Sandra A. Bright, who in collaboration with Professors John Kelly and Clive Williams have had their manuscript “Luminescent ruthenium polypyridyl complexes with extended ‘dppz’ like ligands as DNA targeting binders and cellular agents”, accepted in the RSC journal Dalton Transactions. DOI: 10.1039/c6dt03792e. The work was mainly funded under the SFI PI scheme (2013), the IRC (Postgraduate fellowship to BCP) and via the Marie Curie Fellowship Programme (to SB).

Many congratulations to Raju (Sankarasekaran Shanmugaraju) on the acceptance of his manuscript “Tröger’s base derived coordination zinc polymer for fluorescent sensing of phenolic-nitroaromatics explosives in water”. This work was funded in part though an IRC postdoctoral fellowship to Raju and comes out of a very fruitful collaboration between the TG research group and the Schmitt Group at TCD and the Kitchen Group at University of Southampton. The work is in part based on results obtained by a visiting student Charlyne Dabadie, who under Raju’s supervision spent 6 months in the TG laboratory in 2015, and is to be published in the RSC journal Chemical Science. DOI: 10.1039/C6SC04367D

Many congratulations to Chris Hawes on his manuscript “Flexible porous coordination polymers from divergent photoluminescent 4-oxo-1,8-naphthalimide ligands”, that has been accepted for publication in the ACS journal Inorganic Chemistry. DOI: 10.1021/acs.inorgchem.6b02137. The work was made possible through a postdoctoral fellowship award to Chris from IRC and through the TCD Dean of Research Pathfinder Programme; the work being carried out in part in collaboration with the Schmitt research group in TCD.

Top 25: Article among most downloaded Chemical Science papers

cd-titrations-top25An article from the TG Group entitled “The application of chiroptical spectroscopy (circular dichroism) in quantifying binding events in lanthanide directed synthesis of chiral luminescent self-assembly structures” was among the top 25 most downloaded Chemical Science articles from the last quarter of 2014. The article discusses the use of CD and other spectroscopic techniques to probe lanthanide-directed self-assembly behaviour in solution of chiral luminescent systems – a new approach to understanding the behaviour of these systems.

Dr Oxana Kotova, Dr Salvador Blasco, Dr Jon Kitchen and Dr Miguel Martínez-Calvo from the Gunnlaugsson Group worked in collaboration with Dr John O’Brien and Dr Brendan Twamley from Trinity College Dublin and Dr Robert Peacock in Glasgow on this exciting research.

Most accessed article in Dalton Transactions for 2014

GA-Dalton2014A recent article from the TG Group ‘Synthesis, crystal structure and EPR spectroscopic analysis of novel copper complexes formed from N-pyridyl-4-nitro-1,8-naphthalimide ligands’ was one of the top 20 most accessed Dalton Transactions articles from the 1900+ articles we published in 2014. The list of 2014’s most accessed Dalton Transactions articles has been made available online. This collection contains the 20 articles published in 2014 that received the largest number of downloads in the same year.

The article was authored by Dr Jon Kitchen (now at University of Southampton), Dr Paulo Martinho and Dr Grace Morgan from University College Dublin and Prof Gunnlaugsson.

Dr Jon Kitchen gives a talk at UCD

UCD_logoJon presented some of his work at the RSC Materials Workshop on Multi-Functional Materials in the Centre for Synthesis and Chemical Biology at University College Dublin. The RSC description for the meeting was as follows: “This is a two day meeting for researchers at all levels and is designed as a discursive workshop with a pedagogical element. The main theme is finding ways to use molecular magnets (SMMs and SCO complexes) in real devices. Talks will be delivered by leading experts and younger researchers including postdoctoral and postgraduate researchers.”
