4-Piperidinylimino: A Nearly Linear Head-to-Tail Linking Group for Dipolar Chromophores

Article abstract of DOI:10.1021/jo00007a006

Linkage of the p-aminobenzaldimine and p-nitroaniline chromophores through a piperidine ring gives a compound whose dipole moment is almost exactly the sum of the moments of the constituent chromophores.
