Nitrogen-rich organic compounds have gained attention recently because of their high heats
1
of formation and possible applications as highly energetic materials. Especially, binary CN
compounds such as known polyazides 1, 2, and 3 have been discussed although they are
2
notorious for their extreme sensitivity towards friction and impact. We report here on the
3,4
synthesis and structure assignment of the very explosive title compounds 4, 5, and 6.
Furthermore, some interesting reactions of these polyazides and other nitrogen-rich CN
compounds are presented.

Functional components are becoming more and more important for Materials Science. A high
level of integration of functionalities is targeted and seems to progress until molecular
dimensions. As a consequence, the next generation of functional building blocks may reach
1
picometer dimensions where molecular technology will be required for Materials Science.
Electric interactions dominate highly integrated technology requiring suitable components.
Molecular electronics can be developed in analogy to conventional electronics where
conductors may be replaced by conjugated electronic systems with delocalizable electrons
and resonating circuits by the eigenvalues of molecular structures. Both requirements are
fulfilled by chromophores because of their special electronic structures and distinct lightabsorption. Highly stable chromophores would be ideal components for such applications.
2
The peri-arylenes including the perylene dyes as the most prominent class are very
promising candidates for molecular electronics because of their extraordinary chemical and
photochemical stability. Many synthetic methods are available and will be reported for the
adaptation of this class of compounds to the special requirements of Materials Chemistry.
Complex molecular architectures were established for multichromophoric systems with
special properties such as photo induced electron transfer (PET) and energy transfer (FRET)
for light collection and concentration. The investigation of model compounds indicate that
3
the established theory of FRET has to be altered; novel concepts will be as well presented as
materials with unusual optical properties.

W roku 2008 odkryto nadprzewodnictwo w związku La[O1-xFx]FeAs. Zapoczątkowało to bardzo
intensywne prace, które doprowadziły do odkrycia nadprzewodnictwa w całej klasie
materiałów na bazie żelaza. Najprostszy nadprzewodzący związek z tej rodziny to
niestechiometryczny selenek żelaza FeSe. Częściowe podstawienie selenu tellurem prowadzi
do wzrostu temperatury krytycznej, Tc. W trakcie seminarium omówię wpływ mikrostruktury,
podstawień chemicznych i ciśnienia hydrostatycznego na właściwości nadprzewodzące
monokryształów FeSeTe.
