“…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…”

“…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).…”

“…20,21 Appending the dpm backbone with phenol groups in positions 1 and 9 leads to salen-like ligands with a pseudo-macrocyclic character. 9, [48][49][50][51] This feature prompted their use for the preparation of catalytically active Mn(III) and Ti(IV) complexes. 9 Regarding luminescent species, Burgess and co-workers reported the preparation of a BODIPY derivative 48 and the group of Nabeshima described the synthesis and characterization of fluorescent Al(III) and Si(IV) complexes (Fig.…”

While they may have been overshadowed by the brightness of their BODIPY analogues, dipyrrin based metal complexes have recently appeared as novel interesting luminescent species owing to the development of various synthetic strategies for the preparation of such coordination compounds with appreciable quantum yields and tuneable emission wavelength. Not only the rigidification brought by functionalization of the dipyrrin backbone either at position 5 or positions 1 and 9, but also a careful choice of the ligands present in the complex coordination sphere have been key in these developments leading to bright and stable emitters. At position 5, equivalent to the meso position of a porphyrin, introduction of peripheral groups, such as the mesityl moiety hindering the rotational freedom of this unit, has been particularly targeted, hence limiting a favourable non-radiative deactivation pathway. Regarding positions 1 and 9, their proximity to the metal center has prompted their use for the introduction of additional coordinating units, thus providing a pseudo-macrocyclic character to the ligands. In this perspective article, the different types of modification of dipyrrin as well as the resulting metal complexes incorporating these derivatives, their photophysical properties and their applications in sensing and materials science are reviewed.

“…Numerous studies involving transition metal or main group dipyrrin bisphenols (DPP) complexes have elucidated their physicochemical properties and provided examples for possible applications of these compounds in the areas of fluorescence, [1][2][3][4][5][6][7][8][9] catalysis, [10][11][12][13][14] molecular recognition 5 and anion binding. 15 Our own laboratories have long been interested in tuning and predicting how the redox properties and oxidation states of porphyrins, 16,17 corroles 18,19 and related macrocycles can be systematically varied in nonaqueous media by the judicious addition of pre-selected complexing ligands to solution, by systematic changes in the macrocycle βor meso-substituents and/or by changing the electrochemical solvent/supporting electrolyte system.…”

A series of "N2O2-type" manganese dipyrrin-bisphenols (DPP), formulated as (Ar)DPPMn, where Ar = pentafluorophenyl (F5Ph), phenyl (Ph) or mesityl (Mes), were electrochemically and spectroscopically characterized in nonaqueous media with and without added anions in the form of tetrabutylammonium salts (TBAX where X = ClO4 -, PF6 -, BF4 -, F -, Cl -, OHor CN -). Two major one-electron reductions are observed under most solution condition, the first of which is assigned as a Mn III/II process and the second as electron addition to the π-ring system as confirmed by spectroelectrochemistry. Each Mn III complex also exhibits one or two one-electron oxidations, the exact number depending upon the positive potential limit of the electrochemical solvent. The two oxidations are separated by 580-590 mV in CH3CN, 0.1 M TBAPF6 and are assigned as π-ring centered electron transfers to stepwise form a (Ar)DPPMn III π-cation radical and dication under these solution conditions. Comparisons are made between redox properties of (Ar)DPPMn and manganese(III) porphyrins, corroles and corrolazines each of which contains an innocent trianionic complexing ligand. The redox behavior and spectroscopic properties of [(Ar)DPPMn] n where n = 0, -1 or +1 are also compared to that of other structurally related [(Ar)DPPM] n complexes under similar solution conditions where M = Co II , Cu II , B III or Au III .
