Herein we investigate imaginary third order NLO activity, optical limiting capability and first hyperpolarizabilities of five Ni (II) salen complexes using experimental and theoretical methods. The complexes are tuned to have different NLO response by changing mainly the diimine spacer group. Out of the compounds reported, the one with o‐phenylene spacer group exhibits the highest NLO activity comparable with that of polymers and semiconductors which is followed by the compound with ethylene spacer unit. The order of activity is a direct function of the degree of π‐delocalization. Further all the tested compounds returned outstanding optical limiting capabilities making them excellent materials for fabrication of such devices. The experimental results were substantiated with frontier orbital calculations carried out using DFT at M06/6‐31G* level of theory and complex with aromatic spacer group exhibits least energy gap and highest activity. The total dipole moment, polarizability and first hyperpolarizability were also calculated at the same level of theory which are also in line with the experimentally observed results.

In this work, we explore a modern concept of transmetalation (metal exchange) for the effective recognition of aqueous Al(III) ion. Three different Ni(II) salen‐type Schiff base complexes with different spacer diimine groups were prepared for the metal exchange reaction. These probes recognize Al(III) both colorimetically as well as fluorimetrically. The efficiency in sensing is mainly due to the low emission characteristics of the respective Ni(II) complexes which results in enhanced emission on the formation of Al(III) complex. The geometry of the central Ni(II) metal ion in the probe plays a pivotal role in the sensing action with the highest sensitivity being shown by the Ni(II) metal center with distorted square pyramidal geometry. Further DFT calculations and the energetics involved in the sensing mechanism via the formation of Al(III) complexes substantiates the experimental results.

AbstractIn this study, we report the formation of two quasi‐isostructural polymorphs (α and β) of a Ni(II) salphen‐type Schiff base complex using solvent evaporation technique. The polymorphs are inclusion compounds with guest water molecules exhibiting similar spectroscopic and thermal characteristics. Single crystal XRD (X‐ray Diffraction) analyses reveal the subtle differences in packing and supramolecular interactions which are quantified using Hirshfeld and 2D finger print analyses. Electrostatic potential analysis shows significant difference in potential distribution in the two molecules. The compositional analysis of the frontier orbitals and differences among the atomic charge distribution of the polymorphs are established using DFT (Density Functional Theory) calculations. Apart from highlighting the strength of encapsulation, DFT study substantiates the formation of inclusion compounds through single point energy calculations. Effects of inherent differences in the polymorphs on potential biological activity are probed using in silico molecular docking with B‐DNA and Human Serum Albumin (HSA). The α form shows superior bioactivity while β form excels in water encapsulation.

In the title hydrate, C24H30N2O4·H2O, the organic molecule adopts anEconformation with respect to the azomethine double bonds. The cyclohexane ring is in a chair conformation. The dihedral angle between benzene rings is 79.6 (2)°. Two intramolecular O—H...N hydrogen bonds are present. In the crystal, the components are linked by O–H...O hydrogen bonds and weak C—H...π interactions, generating a three-dimensional supramolecular architecture.
