Synthesis, helicity, and chromism of optically active poly(phenylacetylene)s carrying different amino acid moieties and pendant terminal groups

Article Abstract:

A group of phenylacetylene derivatives bearing L-alanine and L-leucine moieties with different terminal groups are synthesized and polymerized into high molecular weight polymers in high yields. All the polymers have helical conformations, exhibiting large molar ellipticities associated with their backbone absorptions in the CD spectra and the chain helicities of the polymers are tunable by changing their molecular structures and environmental conditions.

Synthesis and characterization of indole-containing chromophores for second-order nonlinear optics

Article Abstract:

Push-Pull indole-containing nonlinear optical chromophores with different acceptor and pi-conjugated moieties are synthesized and characterized. Experimental measures of the second-order nonlinear optical response demonstrated that the chromophores exhibit similar or superior optical nonlinearity compared with their analogues with an aniline moiety as the donor group.
