A Review of Crystalline Multibridged Cyclophane Cages: Synthesis, Their Conformational Behavior, and Properties

This paper reviews the most stable conformation of crystalline three-dimensional cyclophane (CP) achieved by self-assembling based on changing the type of aromatic compound or regulating the type and number of bridging groups. [3(n)]cyclophanes (CPs) were reported to form supramolecular compounds with bind organic, inorganic anions, or neutral molecules selectively. [3(n)]cyclophanes ([3(n)]CPs) have stronger donor capability relative to compound [2(n)]cyclophanes ([2(n)]CPs), and it is expected to be a new type of electron donor for the progress of fresh electron conductive materials. The synthesis, conformational behavior, and properties of crystalline multi-bridge rings are summarized and discussed.

Automated summary

This paper reviews the most stable conformation of crystalline three-dimensional cyclophane achieved by self-assembling based on changing the type of aromatic compound or regulating the type and number of bridging groups. The study found that [3(n)] cyclophanes have stronger donor capability and could potentially serve as a new type of electron donor for innovative electron conductive materials.
