Higher order Stark spectroscopy has recently been introduced and applied to characterize the electrooptic properties of chromophores in bacterial photosynthetic reaction centers.1 In the course of these studies, an unusually large and broad higher order Stark effect with a novel line shape was discovered in the region of the monomeric bacteriochlorophyll absorption band. The origin of this new ...

Starting from a porphyrin functionalized derivative of the L-lysine, three peptides, bearing, respectively, two, four, and eight chromophores, were synthesized using an iterative synthetic strategy based on the choice of mild conditions for the deprotection steps.

The chemical locking of the central single bond in core chromophores of green fluorescent proteins (GFPs) influences their excited-state behavior in a distinct manner. Experimentally, it significantly enhances the fluorescence quantum yield of GFP chromophores with an ortho-hydroxyl group, while it has almost no effect on the photophysics of GFP chromophores with a para-hydroxyl group. To unrav...

Centripetal chromophores based on the s -triazine core with tuneable properties and excellent two-photon absorption were used for construction of high-quality well-transparent emissive polyimide films.
