Synthesis, structures and luminescent properties of red emissive neutral copper(I) complexes with bisphosphino-substituted benzimidazole

Emission and Luminescent Vapochromism Control of Octahedral Cu4I4 Complexes by Conformationally Restricted P,N Ligands

“…Copper(I) complexes have attracted considerable attention as important luminescent materials, due to their low cost and environmental friendliness of copper and potential applications in organic light-emitting diodes (OLEDs). [1][2][3][4][5][6][7][8][9] Many of them provide a tunable phosphorescent emission that can be also affected by external stimuli. [3,[10][11][12][13][14][15][16][17] From this point of view the CuI complexes represent one of the most promising candidates for the design of luminescent sensors due to a large variety of structures, [5,[18][19][20][21][22][23][24] which display temperature sensitivity, [25][26][27][28] luminescent response on organic vapors, [29,30] and mechanical stress.…”

Driving the Emission Towards Blue by Controlling the HOMO‐LUMO Energy Gap in BF2‐Functionalized 2‐(Imidazo[1,5‐a]pyridin‐3‐yl)phenols

“…[4] These compounds are mostly based on rare and expensive transition metals, like platinum(II), [5] iridium (III), [6] ruthenium(II) [7] or rhenium(I) [8] and, therefore, not convenient from an economic point of view. In order to offer a valid alternative to these efficient but high-cost compounds, the interest has been moved to low-cost organic dyes [9] and to coordination compounds of cheaper metals, usually in a d 10 electronic configuration, such as copper(I) [10] or zinc(II). [11,12] Boron is also another interesting element which is known to give fluorescent coordination compounds, [13][14][15] with boron dipyrromethene (BODIPY) being the most renown and studied derivatives.…”

Structural characterization and luminescence properties of trigonal Cu(i) iodine/bromine complexes comprising cation–π interactions

“…The bulky bis-diphenylphosphine-substituted benzimidazole ligand L was prepared in an overall yield of 67%, using a modified procedure reported recently by our group. 35,36 As illustrated in Scheme 1a, the fluorine-substituted precursor R was obtained from simple reductive cyclization. The target ligand L was readily prepared in high yields (85%) by treatment of R with potassium diphenylphosphide in tetrahydrofuran (THF).…”
