‐(bromophenyl)‐Substituted Porphyrins and X‐ray Study of Axial Complexes of Their Zinc Complexes with THF and 1,4‐Dioxane
摘要:
AbstractNew 5‐(4‐bromophenyl)‐3,7,12,13,17,18‐hexamethyl‐2,8‐dipentyl‐ and 5,15‐bis(4‐bromophenyl)‐2,8,12,18‐tetramethyl‐2,8,12,18‐tetrapentylporphyrins (H2P‐1 and H2P‐2) and their zinc metal complexes (ZnP‐1 and ZnP‐2, respectively) were synthesized in high yields by condensation of β‐tetraalkyl‐substituted dipyrromethanes with 2‐formyl‐3,4‐dialkylpyrroles or 4‐bromobenzaldehyde and subsequent metallation. X‐ray analysis data showed the formation of axial complexes of ZnP‐1 and ZnP‐2 with the solvent molecules of THF and dioxane in the solid state. Coordination of ZnP‐1 with dioxane led to polymer multidecker structures.

Thermal oxidative decomposition of samples of crystalline hydrobromide and borofluoride complexes (BODIPY) of a series of 2,2′-dipyrrolylmethenes (HL) was studied by means of thermogravimetry in an atmosphere of air oxygen. An increase in the degree and symmetry of substitution, aromaticity, and the length of the substituents in 4,4′-positions of the pyrrole ligand rings increases stability of the

The heats of solution of a series of substituted pyrroles in benzene, carbontetrachloride, chloroform, DMF, and pyridine were measured by a calorimetric method at 298.15 K. The influence of substituents in the pyrrole molecule on the energy parameters of solvation by organic solvents is discussed.

Reaction of 2-pyrrole carboxylates with Lawesson'sreagent at elevated temperatures results in the corresponding thionoesters, concurrent with the production of a new class of pyrrole annulated with the (1,3,2)-thiazaphospholidine unit. X-ray crystallography was used to identify the pyrrolic thiazaphospholidine, which was found to have unique structural features compared to literature analogues. Addition

Selected complexes were evaluated for their potential in photobiological applications, whereupon all compounds demonstrated in vitro photodynamictherapy effects in HL-60 and SK-MEL-28 cells, with low nanomolar activities observed, and exhibited some of the largest photocytotoxicity indices to date (>2000). Importantly, the Ru(II) dyads could be activated by relatively
