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 are responsible.
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 [27]) 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.
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.
