The key requirements include using a single benzene ring as the core structure, incorporating terminal groups, and adjusting molecular features such as alkyl chains and polar groups to achieve the desired phase behavior. The goal is to create a molecular design that fulfills these criteria, ensuring the material exhibits the necessary properties for practical applications."}
