In particular, ionic liquid crystals (ILCs), a modern class of advanced materials that benefits from the synergistic properties of ionic liquids and liquid crystals, are playing an important role in different areas of knowledge, attracting the interest of the academia and industry, driven by their peculiar tailoring ability. Herein, it comprises a brief synopsis of several pyridinium and picolinium ILCs previously prepared to understand how their mesomorphism and conductivity profiles are affected by small structural changes in terms of the methyl group position and alkyl chain length, providing important insights into future design of functional materials by a simple anionic exchange. Moreover, microwave-assisted reactions were emphasised as a simple and greener synthetic method to prepare ionic liquid crystals through alkylation, which can also be applied to other organic salts.","PeriodicalId":18110,"journal":{"name":"Liquid Crystals Today","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47735881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The event was hosted by Prof. Dr. Frank Giesselmann, Prof. Dr. Sabine Laschat and Dr. Johanna Bruckner, allowing participants from around the world to present their work and exchange ideas on current research in the field of liquid crystals. The conference was held on the campus Stadtmitte of the University of Stuttgart in the city centre, giving the opportunity to explore the capital of the German federal state Baden-Württemberg very easily by foot (Figure 1). This year, more than 80 scientists contributed to the conference with oral presentations and posters. The scientific program consisted of 4 invited lectures, 19 regular talks and 32 poster presentations. The oral presentations of the conference were sorted into 6 different sessions chaired by Prof. Dr. Matthias Lehmann, Prof. Dr. Sabine Laschat, Dr. Johanna Bruckner, Prof. Dr. Jan Lagerwall, Prof. Dr. Frank Giesselmann and Prof. Dr. Michael Giese. The invited talks, which were assigned to 4 of the 6 sessions, covered a wide range of fascinating topics in liquid crystal science and biology. After some opening remarks by Prof. Dr. Frank Giesselmann on behalf of the organizing committee, the conference commenced with Torsten Hegmann (Kent State University, Kent (OH), USA) presenting on phase, morphology and chirality control in B4-phase nanofilaments. On the second day of the conference Elda Hegmann (Kent State University, Kent (OH), USA) demonstrated how 3D porous biodegradable liquid crystal elastomers can be used to emulate native tissue. Joseph E. Machlennan (University of Colorado, Boulder, USA) summarized during his talk, scientific results on the promising class of ferroelectric nematics, as well as the recently discovered polar smectic phase. Finally, the last invited lecture was held by Laurent Douce (Université de Strasbourg/CNRS, France) on luminescent ionic materials for use as tools in biology and for physics to detect neutron radiation. The oral presentations were overall of high interest and provided stimulating scientific discussions during the coffee and lunch breaks afterwards. Various topics were discussed spanning from material investigations to theoretical considerations on complex systems. Some presentations were focused on the photovoltaic effect and also the optoelectronic properties and possible applications of liquid crystalline phases. Another central point of discussion was the synthesis and properties of novel mesogens, such as star mesogens, azulene and lactic acid derivatives, along with making dynamic and reversible covalent systems. Furthermore, new insights into the effects of elasticity and chirality in nematic phases, as well as results on ionic liquids, mesoporous materials, gels, nanoparticles and suspensions were presented.
