A joint experimental and theoretical study revealed the occurrence of highly efficient intramolecular charge transfer and excited state symmetry breaking in a cationic (donor–π–acceptor–π–donor)⁺ quadrupolar compound showing negative solvatochromism.

Two sets of silver–molybdate complexes with L = XR ₃ (X = P, As, Sb; R ₃ = Ph ₃ , Ph ₂ Py) and functionalized pyridine-based ligands have been studied with different techniques.

A promising route to obtain two distinct poly(tannic acid) (PTA) assemblies patterns through solvent-induced supramolecular self-assembly is described.
