Organic holographic materials such as
photorefractive polymers are one of the promising candidates for the
next generation three-dimensional (3D) real-time holographic display.
We are studing the real-time holographic display based on photorefractive polymer.
Recently, we have provided a high-speed photorefractive composite
having a potential of video-rate quality under applied electric field
and a monolithic compound-based polymer composite having a rewritable
capability without applied electric field.

Ferroelectric polymers are a group of crystalline
polar polymers that are also ferroelectric, meaning that they maintain a
permanent electric polarization that can be reversed, or switched, in
an external electric field.
We have successfully fabricated the high-speed
ferroelectric switching device of thin film of the copolymer of
vinylidene fluoride and trifluoroethylene (6:4) under a sinusoidal
electric field from 10 Hz to
100 kHz using a conductive probe chip of AFM. Currently, we are also interested
in studying the application of thin film of nylone 11.

Organic semiconductors offer the possibility of
much simpler fabrication and processing of photonic devices. This is
proving to be a very attractive medium for a range of photonic devices
including light-emitting diodes, lasers, and photovoltaics. Conjugated
polymers are particularly appealing because of their high
photoluminescence quantum yield and ability to be processed from
solution. One application of microstructured semiconducting polymers has
been the distributed feedback (DFB) laser.
Recently, we have found out that the enhanced performances of a
DFB organic dye laser with a high refractive index intermediate layer of
poly(N-vinylcarbazole) laminated between a glass substrate and a laser
dye doped active polymer layer.

Femtosecond pulse lasers provide an industrial
application for precision material processing, in which a focused laser
beam is used to machine any kind of material such as a metal,
dielectric, semiconductor, or polymer. Thus
two-photon-absorption-induced photopolymerization or photoreduction by
the use of femtosecond pulse laser has gained increased interest due to
the capability of manufacturing three-dimensional (3D) structures with
very high feature resolution.
We are now studing the fabrication of 3D structure for many kinds of polymers and polymer composites.

Light-induced reversible transformation between two isomers
with different absorption spectra is referred to as photochromism. Photochromic compounds have attracted much attention
because of their potential for broad use in reversible information
memory media.
Recently, we have found the composite film shows significant
color change in the visible region, and the sensitivity of the
composite to the absorbed dose was achieved based on the high molar
extinction coefficient of the photoisomer.

Currently, many universities, research institutes and companies are conducting research on nanofibers, and various applications are being considered. For example, they are expected to contribute to healthcare, environmental engineering, functional addition, and electronic materials. We are conducting research on environmentally friendly membranes that can separate oil and water on demand, with the aim of contributing to the field of oily wastewater treatment. We are also studying nanofiber-based insulation materials.

Related to the environment, photosensitized reaction and photosensitized biodegradability of polymers
have been investigated using direct measurement of an electron spin resonance (ESR) spectroscopy and
spin trapped method based on ESR spectroscopy. Radical species are assigned from ESR signals, from
which the reaction mechanism can be modeled. Simulation technique also supports the evaluation of
reaction mechanism.

The Photorefractive Polymer research was totally supported by the program for Strategic Promotion of Innovative Research and Development (S-innoavtion), Japan Science and Technology Agency (JST).
We were working to develop a HOLOGRAPHIC Display using photorefractive and photorective polymers. In this project (2009-2015,
7 years), we benefit from collaborations with a number of
researchers including project members of
Norihisa MORIYA (Dai Nippon Printing Co., Ltd.)

We have presented the poly(4-diphenylamino)styrene (PDAS)-based
photorefractive composites with a high-speed response time. The now
composite showed a fast photorefractive response time and large
diffraction efficiency on the basis of well-balanced combination. This
approach provides one of the promising candidates for the future
application of dynamic holographic display.

We have found that polymer composite of monolithic
organic compound of bi-functional compound containing carbazole and
azobenzene units doped PMMA has capability of recording and displaying
new images within a few seconds and fixed at ten seconds and viewing
for a longer time without applied electric field. As you can see the
left media, hologram of an object (coin) is clearly recorded in the
composite and simultaneously reconstructed by a probe beam. The
clearly dynamic 3D hologram without applied electric field had been
shown for the first time in the world.
The present 3D holographic display technology will have a
potential use of 3D digital signage and 3D digital show window etc.

We have proposed that the bi-functional polymer containing carbazole and
azobenzene units doped PMMA has a rewritable capability of holographic stereogram within 38 seconds (100 holos <300 ms/holo> + 80 ms stage transition). As you can see the
left media, a stereogram of object (Hatsunemiku) is clearly recorded and reconstructed, and this image can be easily rewritten in another image (KIT). The
clearly holographic stereograms and system are one of good candidate for 3D signage application.
