Synthesis and structural characterisation of novel bimetallic dipyrromethene complexes: rotational locking of the 5-aryl group

New luminophors based on the binuclear helicates of d-METALS with BIS(DIPYRRIN)S

“…For example, for [Zn 2 (11) 2 ]-[Zn 2 (15) (17) 2 ] complexes with either partially (at α-positions ) or completely unsubstituted terminal pyrroles, the values of ∆λ increases to 75 and 88 nm, respectively (Fig. 8B).…”

“…3) [15,16]. In these compounds, formed by self-assembly, the Zn(II)-cation is coordinated to the dipyrrin chelate and the rotation of pyridyl group, relative to the dipyrrinato unit, is prohibited.…”

“…Luminescent dimeric [Zn(dipyrrin)Cl] 2 complexes. Several H atoms and peripheral groups are omitted for clarity [15,16].…”

“…Several H atoms and peripheral groups are omitted for clarity [15,16]. [33,40,41]; [M 3 L 3 ] -trinuclear molecular triangle [42]; [M 4 L 4 ] -[2×2] grids [43]; [M 6 L 6 ] -hexagon structure (six-core molecular hexagon) [43].…”

“…At the present time two main areas of influence on the fluorescence of dipyrrin luminophors are developed. The first using a new type of ligands with higher rigidity of molecules (N 2 O 2 -type [17][18][19][20][21] and N 3 -type [22]), and the second varies the nature of the complexing agent (d-and f-metals, [13,15,16,23] Ga(III) and…”
