Shaping the 3D architecture of [2.2]paracyclophanes: from selective functionalization to functional luminophores

Over the past few years, [2.2]paracyclophanes (pCps) have attracted considerable attention due to their unique three-dimensional structure and distinctive electronic properties. In this account, we explore various strategies for selective modification of these molecules, with a particular focus on controlling their planar chirality and tuning their photophysical behavior. The versatility of pCps is further illustrated through their broad scope of applications, spanning the development of organic and organometallic luminophores, advances in photocatalysis, and contributions to biochemical research. These diverse applications underscore the strong potential of pCps as key platforms for the design of innovative molecular systems.
