Supramolecular Arrays of Cationic Complexes Containing Pyrazole Ligands and Tetrafluoroborate, Trifluoromethanesulfonate, or Nitrate as Counterions. Crystal Structure of Bis(3,5‐dimethyl‐4‐nitro‐1H‐pyrazole‐κN²)silver(1+) Nitrate ([Ag(Hpz^NO2)₂](NO₃))

Abstract The structures of [Pd( η 3 ‐C 3 H 5 )(Hpz R2 ) 2 ](BF 4 ) (Hpz R2 =Hpz bp2 =3,5‐bis(4‐butoxyphenyl)‐1 H ‐pyrazole, 1 ; Hpz R2 =Hpz NO2 =3,5‐dimethyl‐4‐nitro‐1 H ‐pyrazole=Hdmnpz, 2 ) and [Ag(Hpz R2 ) 2 ](A) (Hpz R2 =Hpz bp2 , A= $\rm{ BF_4^ -}$ , 3 ; Hpz R2 =Hpz NO2 , A= $\rm{ CF_3 SO_3^ -}$ , 4 ) were comparatively analyzed to determine the factors responsible for polymeric assemblies. In all cases, the H‐bonding interactions between the pyrazole moieties and the appropriate counterion and, in particular, the orientation of the NH groups of the pyrazole ligands are determinant of one‐dimensional polymeric arrays. In this context, the new compound [Ag(Hpz NO2 ) 2 ](NO 3 ) ( 5 ) was synthesized and its structure analyzed by X‐ray diffraction ( Fig. 4 ). The Hpz NO2 serves as N‐monodentate ligand, which coordinates to the Ag I center through its pyrazole N‐atom giving rise to an almost linear NAgN geometry. The planar NO $\rm{_{3}^{-}}$ counterion bridges two adjacent Ag I centers to form a one‐dimensional zigzag‐shaped chain which is also supported by the presence of NH⋅⋅⋅O bonds between the pyrazole NH group of adjacent cationic entities and the remaining O‐atom of the bridging NO $\rm{_{3}^{-}}$ ( Fig. 5 ). The chains are further extended to a two‐dimensional layer‐like structure through additional Ag⋅⋅⋅O interactions involving the NO 2 substituents at the pyrazole ligands ( Fig. 6 ).

Multi‐Stimuli‐Responsive Properties of Aggregation‐Enhanced Emission‐Active Unsymmetrical Pt^II Metallomesogens through Self‐Assembly

Chemistry - A European Journal (2019)

Cristián Cuerva J.A. Campo Mercedes Cano Carlos Lodeiro

Herein, we report a series of unsymmetrical bispyrazolate-type PtII compounds that exhibit mesomorphism at low temperatures and photophysical multi-stimuli-responsive properties. These PtII compounds show a great ability to be self-assembled by intermolecular Pt⋅⋅⋅Pt interactions in the solid state, so generating a columnar stacking of molecules that is responsible for the formation of the mesophases. By controlling the nature of the molecular assembly through external stimuli such as the temperature, the pressure, or the presence of vapours or solvents, it is possible to modulate the luminescence behaviour of these materials. The PtII monomers emit a greenish light, whereas aggregation of molecules produces a redshifted emission. These metallomesogens also show a high stability and successive grinding/fuming cycles can be performed without degradation of the sample. The application of these materials is very attractive as rewritable luminescent platforms, and their use is already demonstrated.

Metallomesogens with Luminescent Behaviour: Palladium Complexes Derived from Alkylamide Tetraarylporphyrins

ChemPlusChem (2016)

Nuno M. M. Moura Cristián Cuerva José A. S. Cavaleiro Ricardo F. Mendes Filipe A. Almeida Paz

A series of meso-tetraaryl-substituted free-base porphyrins containing different numbers of alkyl amide chains with different lengths, as well as the corresponding palladium(II) and platinum(II) complexes, were prepared in good yields and were fully characterised. The crystal structure of the palladium(II) complex containing eight alkyl chains with five carbon atoms was unequivocally elucidated by means of single-crystal XRD studies. The thermal behaviour of the new compounds was studied by polarised light optical microscopy and differential scanning calorimetry. Porphyrins with eight terminal alkyl chains containing five and eight carbon atoms, and the corresponding palladium(II) complexes, behave as liquid-crystalline materials, exhibiting lamellar columnar mesophases at temperatures above 80 °C. The number of terminal alkyl chains and the palladium(II) metal centre play a key role in achieving mesomorphic behaviour.
