Flow pattern of a gas bubble in a
room-temperature melt of
poly(methylphenylsiloxane), which contains 0.1%
w/w of BzPO. This 'caged' photoluminescent dye
can be activated in a photochemical reaction; it
was used, among other things, to bestow
multilayer polymer mirrors with a 'hidden'
photoluminescent pattern.

Polarized optical micrograph of
bis(diphenylacetylene)Pt0 crystals. This low
molecular weight organometalic complex was used
as a model compound to confirm the chemical
structure of poly(p-phenylene ethynylene)-Pt0
(PPE-Pt0) networks. The Pt0 cross-links
significantly improve the charge transport
characteristics of these semiconducting
materials.

Lab sample of a fishing line based on the new
polymeric material described
here. The change of fluorescence color
indicates that it may be time to change the
line.

Polarized optical microscopy image (crossed
polarizers) of the nematic phase of
1,4-bis-(a-cyano-4-methoxystyryl)-benzene. The
emission characteristics of blends of a host
polymer and this and similar dyes strongly
depend on the supramolecular architecture of the
system. This dependence can be exploited by
integrating such dyes as deformation sensors in
a polymer of choice.

on the supramolecular architecture of the
system.

Dissolution of an organometallic conjugated
polymer in styrene, shown under illumination
with UV-light. The dissolution of the originally
cross-linked photoluminescent polymer
demonstrates the reversibility of the ligand-exchange
reaction that was employed to create the
metallic cross-links between conjugated
macromolecules. Such cross-links significantly
improve the charge transport characteristics of
these semiconducting materials.
