Pendant organic chromophores have been used to improve the photocatalytic performance of many metal-based photosensitizers, particularly in first-row metals, by increasing π conjugation ligands and lowering energy photoactive absorption band. Using a combination spectroscopic studies computational modeling, we rationalize excited state dynamics Co(III) complex containing pendant pyrene moieties, CoL1, where L1 = 1,1′-(4-(pyren-1-yl)pyridine-2,6-diyl)bis(3-methyl-1H-imidazol-3-ium). CoL1...
New approaches to prepare rarer emitters such as those that are deep-blue needed advance OLED technologies. Here, we demonstrate a series of new platinum(ii) bis(acetylide) complexes [Pt(N-N)(C[triple bond, length m-dash]CPh)2] containing sulfur-bridged dipyridyl ligands (N-N) with various sulfur oxidation states: sulfide (S), sulfoxide (SO) and sulfone (SO2) give access variable emission colors from green deep-blue. Spectroscopic, electrochemical computational studies show mixed character...
Aromatic systems with bridged sulfur units in varying oxidation states have enabled photoresponsive materials for anticounterfeiting and supramolecular assembly. However, only a few sulfoxide-bridged chromophores exhibit photoinduced extrusion, leading to drastic photophysical changes that make them useful as stimuli-responsive materials. Here, we present nitrogen-substituted anthracene (aza-anthracene) bridge different states. Overall, aza-anthracene produces red-shifted green-to-red...
Abstract Luminescent copper(I) complexes presenting thermally activated delayed fluorescence (TADF) have drawn attention as emitters for organic light emitting diodes (OLEDs). While the majority of ligands used nitrogen donor atoms, in this work, we report synthesis and characterization three with diimine ligand 1,10‐phenanthroline aminophosphine‐derived containing piperazine N , N’ ‐dimethylethylenediamine to evaluate their effect into emission properties. The photophysical studies a...
A series of new luminescent bimetallic platinum(II) complexes with stimuli-responsive flexible Lewis pair (FlexLP) ligands are described. The FlexLP consist a dimesitylboron acid and diphenylphosphine oxide base which in equilibrium between the unbound open form adduct, controlled by hydrogen bond donating strength solvent. Spectroscopic techniques density functional theory (DFT) calculations were used to interpret photophysics complexes. All exhibit tunable absorption region 300-500 nm...
Speeding up the phosphorescence channel in luminescent copper(I) complexes has been extremely challenging due to copper atoms relatively low spin-orbit coupling constant compared heavier metals such as iridium. Here, we report synthesis and characterization of three mononuclear with diimines, triphenylphosphine, iodide ligands evaluate effect copper-iodide (Cu-I) moiety into decay pathway. Temperature-dependent photophysical studies revealed combined thermally activated delayed fluorescence...
A series of six new rhenium(I) tricarbonyl complexes [Re(CO)3(N–N)Br] bearing sulfur-bridged dipyridyl (N–N) ligands with three different oxidation states (sulfide (S), sulfoxide (SO), and sulfone (SO2)) are described. Spectroscopic studies show that changing the state influences photophysical properties complexes, 3 6 containing ligand exhibiting a lower energy MLCT absorption band tailing into visible region. Solution-state emission measurements these exhibit readily tunable energies from...
