Another joint paper with our long-standing collaborators, the Manners Group (now at the University of Victoria). Charlie (lead author) and Liam (another former joint student) contributed to a paper on the surface patterning of uniform 2D platelet block co-micelles – published in ACS Macro Letters! We show the formation of rectangular platelets containing two block copolymers with different coronal chemistries. On addition of a solvent that is only able to solvate the corona of one block, colloidally stable micelles with patterned surfaces via coronal collapse are formed.
Well done to all involved in this productive and long-standing collaboration!
Continuing the Faul Research Group’s long-standing collaboration with Yaozu and Wei (and Yaozu’s group at Donghua University in Shanghai), our latest paper just appeared in Chemistry of Materials! And of course great to have Arne Thomas (TU Berlin) involved in the study as well!
In a new study that just appeared online in the Journal of Materials Chemistry A, work with former group member Jie continued to explore Hansen Solubility Parameters as a tool to tune structure and function in porous materials! Congrats Jie!
Here we expand our recently reported Bristol-Xi’an Jiaotong (BXJ) approach using simple salts to fine-tune the porosity of conjugated microporous materials synthesized by various reaction approaches, including Buchwald-Hartwig (BH), Sonogashira-Hagihara, oxidative coupling and Suzuki cross-coupling.
A paper by our collaborators at the National Centre for Nanoscience and Technology in Beijing (Prof Zhixiang Wei and his group, with contributions from Charl) was just accepted. The lead author is Kamran, who visited last year and October (and still attends some group meetings and social events, virtually!)!
The paper, in the RSC’s Sustainable Energy & Fuels, discusses the use of a coaxial nanocomposite of an active anthraquinone-based Covalent Organic Framework (AQ-COF) and carbon nanotubes for Lithium Ion Battery applications. AQ-COF was grown on the surface of carbon nanotubes (AQ-COF@CNTs) through an in-situ polymerization to improve the conductivity and to facilitate the electrochemical properties. Please read here for further details! Congratulations to Kamran and the other authors!
A paper on switchable azobenzene-based liquid crystals by Luke, who visited in July 2019, and supervised by collaborator Rico Tabor (and co-supervised by Charl!), just appeared online in the RSC’s PCCP.
The study, entitled “Structural relationships for the design of responsive azobenzene-based lyotropic liquid crystals” explored light-responsive binary (azobenzene + solvent) lyotropic liquid crystals (LCs), and investigated their phase behaviour by structural modification of simple azobenzene molecules. A range of scattering and microscopy techniques were employed to explore the influence of structure and light-switchable nature on phase behaviour in these very interesting systems. Well done to Luke and all collaborators!
A paper by Pan (with collaborators from the Schroeder Group at UCL and Chemical Engineering in Bath) was just accepted for publication in ACS Applied Materials & Interfaces. The study, on the use of new conjugated microporous polymers for gas and vapour sorption and detection, provides insight into the use of CMPs for applications very relevant to the issues of indoor air quality and sensing.
The paper has now appeared as just accepted! Congratulations to all involved!
Charl also had to the opportunity to catch up with Yaozu, Wei (former FRG members now at Donghua), as well as collaborators Prof Hiroshi Kitagawa (Kyoto, Japan), and Dr Samuel Chigome (BITRI, Botswana).
A new study, where Charl contributed to on-going collaborative activities with former postdoc (and now professor at Donghua) Yaozu Liao, was published in Chemical Engineering Journal. This study explored modified tetraphenylmethane (TPM)-based POPs i.e. mPTPMs (synthesized via Buchwald-Hartwig cross-coupling of a tetrakis(4-bromophenyl) methane core and selected aryl diamine linkers, followed by a crosslinking alkylation strategy using diiodomethane as a crosslinker).
This new strategy offers mPTPMs with high surface areas, uniform ultramicropores where porous properties are readily controlled by the substitutions of linkers and the crosslinker. More details on the paper entitled “A crosslinking alkylation strategy to construct nitrogen-enriched tetraphenylmethane-based porous organic polymers as efficient carbon dioxide and iodine adsorbents” to follow soon!
We found that key features of the one-dimensional (1D) morphologies were dependent on both the polarity of the solvent medium and temperature. Read the paper for more details – the 11th collaborative paper with the Manners group!
