About the Project
Research in low molar mas systems involves liquid crystal dimers containing two liquid crystal groups connected by a flexible spacer . These exhibit unique properties including novel intercalated smectic phases and most recently, been shown to exhibit a new type of liquid crystal phase, the twist-bend nematic phase [2-5]. This project will involve the synthesis of new dimers designed to show this fascinating new phase. Our most recent discovery has involved the identification of a new family of heliconical smectic phases.
The physical characterisation of new materials will include a range of techniques including polarised light microscopy, differential scanning calorimetry, thermal gravimetric analysis coupled with mass spectrometry, temperature dependent Fourier transform infra red spectroscopy, dynamic and thermal mechanical analysis, and X-ray diffraction. The balance between organic synthesis and physical characterisation may be tailored to suit the student’s interests and background.
The successful candidate should have (or expect to have) a UK Honours Degree (or equivalent) at 2.1 or above in Chemistry
Knowledge: Organic and physical chemistry
