Thiosemicarbazone Structures Including Nickelophilic Interaction as Well as Both Hydrogen Bonding and π-π Stacking Interactions: NLO, Electrochemical, Chromism, and Spectroelectrochemical Properties.

Introduction Since Lehn was awarded the Nobel Prize for his work on supramolecular chemistry in 1987, , the synthesis of new supramolecular structures has been the subject of extensive research and has led to unconventional new themes such as host–guest chemistry, nonlinear optical (NLO) properties, 3D-/4D-printing systems, gas adsorption, and gas storage and separation. Physical interactions, such as intra- or intermolecular hydrogen bonding, π–π stacking of arenes, van der Waals forces, electrostatic interactions, and metal–metal contacts, are considered highly significant, as they contribute to the formation of supramolecular and polymer structures.
