Charge-transfer processes in metal complexes enable luminescence and memory functions

Ultrafast and long-time excited state kinetics of an NIR-emissive vanadium(iii) complex I: synthesis, spectroscopy and static quantum chemistry

“…11 Finally, these properties enable the efficient population of the photoactive and luminescent longlived triplet metal-to-ligand charge transfer ( 3 MLCT) states as lowest excited states aer intersystem crossing (ISC). 12 Aiming at a sustainable future photochemistry less dependent on rare and precious metals, Earth-abundant metals are currently heavily explored and novel concepts have been put forward [13][14][15][16][17][18] including some second row metals, [19][20][21][22] but in particular the rst row transition metals. [13][14][15][16][17][18] The 3d transition metals possess a weaker ligand eld splitting 10 and smaller SOCs 11 posing severe challenges to the design of the excited state landscape, 14 yet several recent breakthroughs have been reported, e.g.…”

Synthesis of benzo[b]phosphole‐based alkynylgold(I) complexes with resistive memory properties modulated by donor–acceptor chromophores

“…Organometallic complexes with charge transfer moieties have gained a lot of attention in the design of functional materials and organic electronics 1 . With a judicious structural design, the electronic properties of these molecular complexes can be readily tuned to perform different functions 1 .…”

Facile Charge Transfer between Barbituric Acid and Chloranilic Acid over g-C3N4: Synthesis, Characterization and DFT Study

“…The charge transfer process (CT) has been extensively investigated in material science [1][2][3][4], biological systems [5,6], and crystal engineering [7,8]. The CT process is initiated between high electron donor molecules (Donors) and electron-deficient molecules (Acceptors) to form stable CT adducts [9,10].…”
