Outline of Final Research Achievements

I examined the synthesis of multilayered [3.3]para and metacyclophanes to perform a systematic study on the transannular π-electronic interaction by both through-space and/or through-bond electronic interactions.
In addition, in the donor (D) -bridge (B)- acceptor (A) systems that incorporated [3.3]cyclophanes, I succeeded the synthesis of all four possible isomers of dibromo[3.3]paracyclophanes, i.e., pseudogeminal, pseudoortho, pseudometa, and pseudopara isomers. In the [3.3]metacyclophane systems, I succeeded the synthesis of three- and four-layered dibromo[3.3]metacyclophanes, and incorporated the acceptor (naphthalimide) and the donor (carbazole) moieties into both ends benzene rings.
