The company said that Perkinamine chromophores
are its base chromophore
architecture and the foundation of its unique electro-optic materials platform.
First, assume that there are a fixed number of initial sites, [N.sub.p0], of chromophore
precursors per volume that can absorb a photon and be converted into a chromophore
Moerner suggests that changes in the charge around the chromophore
To furnish a deeper and detailed mechanistic understanding of the photoisomerization reaction of those green fluorescent protein chromophore
based molecular switches, semiclassical nonadiabatic molecular dynamics simulations were performed for a molecule 4-benzylidene-2-methyloxazol-5(4H)-one (BMH, named as 2e in ) in our group.
The organic NLO chromophore
chalcone derivative 1-(4-methylphenyl)-3-(4-N,N-dimethylaminophenyl)-2-propen-l-one (MPDMAPP) is synthesized using standard method (Claisen-Schmidt reaction method) (4) and the molecular structure of this compound is shown in Fig.
Samples with poor or no UV chromophore
can be purified by connecting an external detector such as a refractive index or evaporative light scattering detector (ELSD) to the system.
Dragan (Institute of Macromolecular Chemistry, Romania) collects information from the literature as well as original contributions in the field of ionic (co)polymers and hybrids such as self-assembled multilayers, ionic polymers containing azobenzene chromophore
, phase separation processes, chelating ion exchangers, polymer electrolytes, functionalized solid surfaces, ionic hybrid hydrogels, and nanocomposites for polymer electrolytes.
Upon absorption of a photon by a chromophore
, an electron is promoted from the singlet ground state (SO) to an intermediate vibrational level of the excited singlet state (S1).
* Recently launched RealanA(r) Black MF-PV for wool that is based on a newly developed chromophore
which is completely free of heavy metals.
In chemical crosslinking method, the crosslinking temperature must be higher than the [T.sub.g] of a polymer to ensure an efficient poling of the chromophore
before the crosslinking reaction begins.
It is designed with the dye structure containing hard segment (chromophore
) and soft segment (auxochrome) to get higher dyeing fastness.
