Two forms of a novel accordion-shaped non-linear optical polymer (NLOP
) based on cis- and trans-1,2-diaminocyclohexane and o-xylyl linkages
were characterized by solution- and solid-state NMR spectroscopy. Mode
l compounds and the monomers for both the cis and trans forms of these
polymers were also investigated. The cis form is less rigid than the
trans form, as demonstrated by the fluxional behavior of the cis model
in the solution state.
