1. Mesomorphic biopolymer and hydrogel systems
Anisotropic composites based on LC cellulose
derivatives
Several cellulose derivatives form lyotropic
solutions in acrylic monomers, what makes
possible the creation of anisotropic composites
with frozen mesophase by photopolymerisation of
acrylic component. By proper choice of the
cellulose derivatives and polymerisable solvents
(e.g. acrylic acid (AA)), one can design the
polymer composites with desired properties.
Polarised micrographs and TOA results show that
the anisotropy of the composites is reversible
after isotropisation. Dielectric spectroscopy and
dynamic mechanical analysis show molecular
dynamic relaxations, which are combination of
relaxations characteristic of the both
components.

1. Mesomorphic biopolymer and hydrogel systems
Liquid crystalline (LC) networks formed by
photoinitiated chain crosslinking

h?
In the 1990s a new period began with
LC-precursors of LC-polymer networks. The
physical phenomena behind these systems are
complicated but have a great potential in many
applications and are expected to play a dominant
role in the field of polymer networks in future.
The photoinitiated chain crosslinking technique
finds diverse applications UV curable coatings,
photoresists, printing processes and composite
preparation.
LC-monomers or their mixtures
LC-network
Fig.2
When LC-monomers are photopolymerised in the
bulk, the so-called LC-networks are produced
(Fig.1). The process of photocrosslinking of
LC-monomer mixtures has to be faster than the
phase separation. In contrary to the liquid
crystalline phases of low molecular weight
materials they exhibit a stabile molecular
organisation up to the degradation temperature.

  directions

  move, at the same time

  the polymer chain

6. Conducting polymer composites
Reticulate doped polymers
The technique of reticulate doping of polymers,
originally elaborated in this laboratory,
consists in crystallization of low molecular
weight organic materials (e.g. the so called
"organic metals") in situ, in polymer matrix.
Very fast, diffusion limited crystallisation
leads to formation of highly non-equilibrium
micro- and nano-crystallites (dendrites,
whiskers, very thin plates) forming continuous,
conducting network penetrating the polymer
matrix. These composites show extremely low
percolation threshold - below 0.01 !

6. Conducting polymer composites
Reticulate doped polymers
Different modifications of the reticulate doping
technique allow to produce highly oriented
composites, showing very strong anisotropy of
electrical and optical properties (zone-casting
technique) or surface conducting bi-layer
composites (two-step reticulate technique).
Composite of polyethylene with 1 wt. of TTT-TCNQ
obtained by zone-casting shows very strong
electrical anisotropy, higher than 106 !
Bilayer composites of PC with very thin layers of
(BEDT-TTF)2I3 nanocrystallites show metal-like
conductivity and an onset to superconductivity at
low temperatures.

7. Electro-optical properties of organic materials
Photo-generation, trapping and recombination of
charge carriers in polysilanes substituted with
carbazole chromophores

• In unsubstituted polysilane (PMPSi) weak TL peak
  shows, that only shallow traps of charge carriers
  are present.
• With increasing content of the carbazole side
  groups the intensity of the TL peak increases and
  its position shifts towards higher temperatures
  indicating increasing population of deeper traps
  and more effective recombination.

23
7. Electro-optical properties of organic materials
Spectral analyses of thermoluminescence for
polysilanes
Spectral analyses of TL indicate that for higher
degree of substitution with carbazole
chromophores the excimeric emission (at longer
wavelength) dominates in the spectra, due to
formation of nano-aggregates by carbazole side
groups.
24
7. Electro-optical properties of organic materials
Photogeneration quantum yield in photoconducting
charge-transfer complexes of substituted
polysilanes and of PVK with TNF as studied by
Surface Potential Decay (SPD) technique

• TL and SPD studies show, that in fully
  substituted polysilane (PSiK) nanoaggregates of
  carbazole chromophores are formed, leading to
  more effective recombination and in a consequence
  to decrease of the photogeneration yield.
• PSiK (105) copolymer exhibits the optimal
  photoconductive properties among the studied
  polysilanes.

25
7. Electro-optical properties of organic materials
Photogeneration and photovoltaic effects in
discotic LCs
Surface potential decay technique shows that in
pure perylene derivative only negative mobile
charge carriers were photogenerated, in pure
HBC-PhC12 only very weak photogeneration in the
visible range was detected, but in the mixtures a
synergetic effect of photogeneration of both
positive and negative mobile charge carriers was
observed. The above obtained results were
correlated with performance of the photovoltaic
devices with active layer made of the mixtures of
the DLCs and perylene derivative. It was found,
that the power conversion efficiency and
stability of the solar cells is dependent on the
composite morphology, which can be controlled by
the temperature of preparation.

7. Electro-optical properties of organic materials
Characterisation and adventages of dye synsetized
solar cells (DSSCs)
1. The processes of light absorption and charge
transport in DSSCs occur in different materials,
what prevents the premature recombination of
electron and holes. 2. Incident light is
absorbed by a dye that is coated as a monolayer
on a transparent nanoporous semiconductor. The
porosity results in an enlargement of the
effective surface area up to a factor of 1000.
More dye molecules can be absorbed onto the
surface, which guarantees sufficient light
absorption. 3. Photoexcitation of dye leads to
injection of electrons in the conduction band of
the oxide. 4. The oxidized dye is permanently
reduced back by redox medium (electrolyte) or by
solid hole conductor. 5. Maximum power conversion
efficiency up to 11 can be achieved from single
cells on small active areas.

characteristic parameters for DSSCs with liquid
