Synthesis and Structures of π-Extended [<i>n</i>]Cyclo-<i>para</i>-phenylenes (<i>n</i> = 12, 16, 20) Containing <i>n</i>/2 Nitrogen Atoms

Abstract

[n]Cyclo-para-phenylene congeners of n = 12, 16, 20 with n/2 nitrogen atoms were synthesized via Pt-mediated one-pot macrocyclization reactions. The reaction allowed diversification of participatin...
