Abstract:

Macrocyclic receptors have served as the principal tools of supramolecular chemistry because of their innate molecular recognition and complexation capabilities. They have also increased research interest in modern supramolecular chemistry because of their practical applications. Leaning towerarenes, a new family of synthetic macrocycles, have various applications in crystal engineering and other related fields owing to their excellent solubility and crystallization, flexible backbone, and superior host-guest properties. In this paper, we summarize the applications of leaning towerarenes from the perspective of crystal engineering. Particular attention is paid to the correlation between their structural features and supramolecular functions. We hope this will stimulate students' interest in crystal chemistry and beyond.

Key words: Crystal engineering, Supramolecular chemistry, Macrocyclic chemistry, Host-guest chemistry
