The focus of recent organic chemistry research has been on developing liquid crystals that exhibit low crystal-mesophase transition temperatures and extensive phase lengths. Achieving a single-component, room-temperature liquid crystal with a broad mesophase range is uncommon, prompting the exploration of mixtures. Combining two or more low melting materials may yield a room-temperature mesomorphic mixture capable of exhibiting a wide mesophase length, addressing this challenge in the field.

Exploring the fascinating realm of liquid crystals, this book delves into their unique properties that bridge the gap between solid crystals and isotropic liquids. With over 35 known types and ongoing research, it highlights the advancements in technology that have led to improved and more affordable displays. The text emphasizes the continuous growth in research and development over the past three decades, suggesting the potential for future discoveries in this dynamic field.

The study focuses on the influence of naphthalene moieties on mesophase transition temperatures in liquid crystal materials. It presents a homologous series of azoesters and Schiff base cinnamates, examining how variations in alkyl chain length and the presence of an ethylene linking group affect mesomorphic properties. The research aims to enhance the understanding of phase transition behaviors in these compounds, contributing to advancements in liquid crystal technology.

Focusing on the significance of terminal groups in liquid crystal compounds, this book serves as a valuable resource for MSc Chemistry students and researchers. It emphasizes how terminal substitutions can enhance the stability of mesophases, revealing that increased molecular polarizability, without a substantial increase in breadth, contributes to greater thermal stability. The text provides insights into the relationship between molecular structure and properties, making it essential for understanding liquid crystal behavior.

This study presents analytical methods for various beta blockers, including Atenolol, Acebutolol, and others, addressing their stability issues. It discusses their spectrum of activity and mechanisms of action, along with detailed descriptions of analysis in both single and combined dosage forms, and outlines current trends in method development and validation.

Flüssigkristalle zeichnen sich durch ihre einzigartige Phase aus, die Eigenschaften zwischen Flüssigkeiten und festen Kristallen vereint. Sie besitzen eine Ordnung in einer oder zwei Dimensionen und weisen gleichzeitig Fließfähigkeit auf. Ihre Entstehung ist eng mit der molekularen Asymmetrie und entropischen Faktoren verknüpft. Die fortschreitende Forschung in diesem Bereich eröffnet neue Anwendungsmöglichkeiten, wodurch Flüssigkristalle zunehmend an Bedeutung für moderne Technologien gewinnen. Im Gegensatz dazu zeigen kristalline Materialien eine vollständige dreidimensionale Ordnung.
