| The STC has constructed an HRS apparatus based on a Ti:sapphire pumped
optical parametric oscillator. First, the output of a Ti:Sapphire oscillator
(Spectra Physics Tsunami) can be used for excitation from 740 to 1000 nm.
Further tunability is achieved by using the oscillator to pump an optical
parametric oscillator (Spectra Physics Opal) which provides output ranging
from 1.1 to 2.5 nm. This system is now operative, and has been used to
provide estimates for approximately 16 chromophores recently developed
by researchers involved in the STC.

| For many proposed applications and studies in the STC, reasonable quantities
of pure material are required. A new shared synthetic scale-up and purification
facility has been constructed recently in the Department of Materials Science
and Engineering (480 sq. ft.) at UW to provide synthetic capabilities for
preparation of materials on quantity scales and purity compatible with device
fabrication.
The facility is equipped with fume hoods with vacuum and gas
lines, various scale-up organic solvent distillation and purification systems,
analytical and preparative mode gel permeation chromatography systems with
various columns (Waters Breeze HPLC System, Waters Corporation), medium
pressure silica-gel based chromatography columns, and large scale laboratory
glassware in addition to more common organic laboratory equipments such
as vacuum and drying ovens, recirculating chillers, refrigerator/freezer,
rotary evaporator, balances, stirrer hot plates, and chemical and solvent
storages systems. To complete the facility, large scale reaction and purification
assemblies and high vacuum purification systems are still required.
By integrating
the functions of the existing synthetic and material characterization capabilities
of various laboratories and departments of the STC team members, we are
planning to improve the facility to establish a practical synthetic scale-up
and purification capabilities of the STC available to all team members.

| The Center has developed a state-of-the-art facility for the purification
of organic materials, the fabrication and testing of organic photonic and
electronic devices. The facility is comprised of an automated high vacuum
deposition system with four organic sources and two high power sources for
metals and oxides (co-deposition capabilities). It is integrated with a
double glove box (one dry and one wet with integrated spin-coater) that
enables the fabrication and testing of new devices in inert atmosphere.
A second glove box is equipped with a microprobe station and a semiconductor
parameter analyzer.
The facility is fully equipped for the testing of organic
light-emitting diodes, organic field-effect transistors, and organic solar
cells.
