Thermoelectric materials are of great practical and scientific interest as they can 'upcycle' waste heat into electricity. Porous framework materials, such as the crystalline metal-organic frameworks, in particular have recently been highlighted as desirable candidates for thermoelectric applications as they may couple very low heat conductivity with appreciable electric conductivity.The project will entail the synthesis of fused aromatic rings with amino and thiol functionalities, and their incorporation into metal-organic frameworks in order to achieve 2D layered materials displaying 1D channelled crystal structures and displaying high electric conductivity with low thermal conductivity. Thermoelectric properties will be tested as part of the project, which in turn will be used to optimise the materials' composition and structure to obtain superior metal-organic framework-based thermoelectric materials. The project will involve a level of materials' processing, including but not restricted to the synthesis of the above metal-organic frameworks as thin films.

热电材料具有很大的实用性和科学性，因为它们可以将废热“升级”为电能。多孔骨架材料，如结晶金属有机骨架，特别是最近已被强调为热电应用的理想候选者，因为它们可以将非常低的热导率与可观的电导率相结合。该项目将需要合成具有氨基和硫醇官能团的稠合芳环，以及将它们结合到金属-有机骨架中，以获得显示1D通道晶体结构并显示高电导率和低热导率的2D层状材料。热电性能将作为该项目的一部分进行测试，这反过来将用于优化材料的成分和结构，以获得基于上级金属有机框架的热电材料。该项目将涉及一定程度的材料加工，包括但不限于将上述金属有机框架合成为薄膜。
