The results obtained demonstrate a new approach for the
selective synthesis of novel 1D organometallic–organic hybrid
polymers 5–8 based on the reaction of the organometallic P2
ligand complex [Cp2Mo2(CO)4(Z2-P2)] (A), the copper salt
[Cu(CH3CN)4]BF4 (B) and the flexible pyridine-based linkers
1–4. This is possible due to the liability of the Z2-coordinated P2
units, which could be easily substituted by the pyridine-based
organic linkers 1–4. In these aggregation reactions, the flexi-
bility of the linkers 1–4 plays a ‘‘positive role’’ instead of the
usual ‘‘destructive role’’ in directing the synthesis towards
selective product formation since those linkers can easily adopt
their backbones to afford the thermodynamically favored poly-
mers. Current investigations focus on the use of rigid linkers
with defined lengths and functionalities. The reactions of those
linkers with the P2-based dimer precursor C are expected to be
directionally leading to selective products with the possibility of
a fine tuning and control of the sizes of the cavities formed.
In addition, the incorporated functionalities could play a role in
the host–guest chemistry of defined host molecules.
