Four red compounds for color filter (CF) pigments in which phenyl, 4-chloro-phenyl, 4-fluoro-phenyl and pentafluorophenyl groups are substituted to 5-position of dipyrrinato group based on bis-dipyrrinato ligand were synthesized, and physical properties f
Synthesis of porphyrins bearing trans-thiols
Jagessar, Raymond C.,Tour, James M.
, p. 111 - 113 (2000)
(matrix presented) A route to porphyrins bearing frans-thiols is described using a thioacetyl-containing aldehyde or a thioacetyl-containing dipyrromethane in the presence of catalytic BF3·OEt2 followed by oxidation. Metal complexation and ammonium hydroxide induced acetyl removal provides a route to these important molecular systems for future electronics experiments in which the thiols would serve as the adhesion points to gold probes.

A series of mono- and di-brominated BODIPYs (1-5) was synthesized and characterized with a view to study the performance of dyes towards antibacterial activity. Regioselective bromination at the 2- and 2,6-positions of the BODIPY core was achieved with quantitative yield. The bromination of meso-(4-hydroxyphenyl) BODIPY (5) yielded an unexpected dibromo derivative, where the bromine groups were installed at the 3,5-positions of the phenyl ring rather than the 2,6-positions of the BODIPY core, which is confirmed and supported by UV-visible, fluorescence, and 1H NMR spectroscopic analyses, electrochemical studies, and also by single crystal X-ray crystallography. We observed a red shift of ～16 nm in the absorption and 20-29 nm in the emission spectra in CH2Cl2 for the installation of each bromine group at the BODIPY core. The small difference between the first reduction potentials of the parent and dibromo derivative (5 and 5b) reveal that dibromination does not occur on the pyrrolic moiety. The intermolecular interactions involving C?H, F?H, H?H, and Br?H are the key factors in stabilizing the molecular crystal packing. The antibacterial properties of these dyes were investigated and the brominated derivatives showed better antibacterial effects than their corresponding parent BODIPYs, particularly the unusual dibromo derivative, 5b.
Green Chemistry for Preparation of Oligopyrrole Macrocycles Precursors: Novel Methodology for Dipyrromethanes and Tripyrromethanes Synthesis in Water
Karl, Vladimir,Vasek, Petr,Dolensky, Bohumil
, p. 1126 - 1136 (2004)
A novel methodology for preparation of linear oligopyrroles is presented. Synthetic protocol uses water as a solvent for acid catalysed condensation of an aldehyde or ketone with unsubstituted pyrrole. While the most procedures for the above-mentioned com
Meso- and axially-modified IrIIItriarylcorroles with tunable electrocatalytic properties

The synthesis of three A2B type Ir(III)triarylcorroles with meso-aryl substituents that provide electron donating (push) and withdrawing (pull) properties and three A3 type IrIIItriphenylcorroles with differing pyridine axial ligands is reported, along with their structural characterization. An analysis of the structure-property relationships in the optical and redox properties has been carried out by comparing their optical spectroscopy and electrochemistry to trends predicted in DFT and TD-DFT calculations. The results demonstrate that A2B type IrIIItriarylcorroles are highly efficient electrocatalyzed oxygen reduction reactions (ORRs) and that their reactivity can be modulated by modulating the electronic structure by changing the nature of the meso-substituent at the B-positions, and even axial pyridine ligands.
Single azopyridine-substituted porphyrin molecules for configurational and electronic switching
Matino, Francesca,Schull, Guillaume,Jana, Umasish,Koehler, Felix,Berndt, Richard,Herges, Rainer
, p. 6780 - 6782 (2010)
A new azopyridine functionalized Ni-porphyrin was synthesized as a model compound for deposition and switch on surfaces. Two geometrically and electronically different states of single molecules on Au(111) were found by scanning tunneling microscopy/spectroscopy and analyzed with density functional calculations.

Synthesis of dipyrromethanes in aqueous media using boric acid
Singhal, Anchal,Singh, Snigdha,Chauhan, Shive M. S.
, p. 144 - 151 (2016)
Boric acid acts as an efficient and green catalyst for the condensation reaction of pyrrole and aldehydes in aqueous medium to produce parallel library of dipyrromethanes including new compound analogue, meso-acetyldipyrromethane in moderate to good yield. The use of boric acid as catalyst and selective reactivity of aldehydes over ketones in its presence, and water as reaction medium are important attributes in the present protocol.
