Influence of the Position of the Connecting Spacer of the Chromophore on the Nonlinear Optical Response Open
A new chromophore, C1 , based on a similar DπA‐structure as in the FTC ‐chromophore but with a hydroxyalkyl spacer perpendicular to the direction of the dipole moment was synthesized. Both chromophores and the CLD ‐chromophore were used to…

Synthesis of Chiral Helical Chromophore‐Functionalized Polybinaphthalenes Open
Chromophore‐functionalized, chiral, helical polybinaphthalenes with acetylene linkage have been prepared by functionalization of precursor polymers. The chromophores are chirally ordered in these materials which, together with the many pos…
Influence of the composition of in-vitro azo-reducing systems on the degradation kinetics of the model compound amaranth Open
The purpose of this study was to investigate the influence of the composition of in-vitro azoreducing systems on the degradation kinetics of the model compound amaranth. The degradation kinetics of amaranth were determined under anaerobic …
Second‐order nonlinear optical properties of a chromophore‐functionalized polypeptide Open
The attachment of a nonlinear optical chromophore to a polypeptide backbone yields a structure in which the chromophores are oriented non‐centrosymmetrically, likely due to the supramolecular helix structure of the polypeptide. This struct…
