The discovery, design and synthesis of new organic molecules and
understanding the intricate mechanisms by which they interact leads to exciting
advances in silver halide and digital imaging technology. Imaging chemicals are
complex multifunctional molecules often requiring highly selective functional
group transformations of several iterations. State of the art design techniques
and synthetic methodologies are employed by Kodak scientists to arrive at the
desired target structures. Research in synthetic organic chemistry involves both
long range exploratory research and mission oriented research.
synthesis of new organic materials ranges from milligrams to metric tons.
Discovery phase of research involves modern tools such as combinatorial
chemistry in which multiple reactions can be carried out on solid phase supports
or in solution in a parallel fashion followed by automation, purification and
characterization. Quantitative Structure/reactivity relationships are generously
used to design novel compounds. On larger scale, process development using
experimental design is used for optimization of multi-kilogram syntheses,
leading to commercialization.
Organic chemists thrive in a highly interdisciplinary and team environment.
Understanding the function and interactions of complicated molecules is
accomplished by physical organic chemists. From measuring reaction rates to
calculating excited states, important mechanistic information is vital to the
design of improved imaging chemistry. Large molecules are studied by
computational science, molecular modeling and x-ray diffraction to understand
how their structure can effect their performance.
The characterization of organic compounds is supported by state-of-the-art
analytical facilities for high pressure liquid chromatography, mass spectra,
nuclear magnetic resonance, and infrared spectrophotometry.
print and Color slide films require the design of dyes to spectrally sensitize
silver halide, image forming couplers, stabilizers for improved image stability,
organic reducing agents, organic oxidizing agents, ultraviolet filter dyes which
remain in the film or paper, filter dyes that are removed during processing and
accelerators and inhibitors of silver development. In addition to these
materials color negative film requires color masking image formers, and image
modifying chemistry. All these materials have to be optimized for performance
and incorporated into the gelatin matrix of photography conforming to specific
Thermal dye transfer and ink jet printing systems are capable of producing
very high quality images directly from digital files. Novel dyes have been
designed that will work in these systems and yet provide the color and stability
of traditional photographs.
High quality digital color proofing systems for the printing industry are
based on Kodak’s laser dye transfer technology. Specially designed dyes match
the colors of the printing inks and convert laser light to heat.
"Invisible" dyes will allow the embedding of additional information
("metadata") into photographs that will prevent misuse of copyrighted
images, enable images to be readily sorted and even provide sound bites for the
More recently, organic light emitting diode ( OLED) materials are emerging as
potential replacements for flat-screen displays in future electronic products.
