Use of Hydrogen Bonds to Control Molecular Aggregation. Behavior of a Self-Complementary Dipyridone Designed to Self-Replicate

Persico, Francois,Wuest, James D.

, p. 95 - 99 (1993)

In principle, the simple dipyridone 4 encodes enough chemical information to allow it to self-replicate by acting as a template for the assembly and controlled oxidative coupling of ethynylpyridone subunits 5 and 6.This could occur by the formation of ter
