(5-tert-Butylporphyrinato)copper(II), a nonplanar porphyrin with only one sterically demanding meso residue
SENGE, MATHIAS (2011)The title compound, [Cu(C24H20N4)], is a rare example of a porphyrin carrying only one substituent. Its crystal structure exhibits two molecules in the asymmetric unit. The bulky meso tert-butyl residue gives rise to a ... -
7-Nitro-5,10,15,20-tetraphenylporphyrin Dichloromethane Solvate
SENGE, MATHIAS (International Union of Crystallography, 1998)The title compound shows significant conformational distortion in the vicinity of the [beta]-nitro group. This is attributed to steric interaction between a meso-phenyl and the [beta]-nitro group. The overall degree of ... -
A2B2-type push-pull porphyrins as reverse saturable and saturable absorbers
SENGE, MATHIAS; BLAU, WERNER (2007)A2B2-type push?pull porphyrins with a strong intramolecular dipole moment have been prepared via Heck and Suzuki coupling reactions as novel materials for use in nonlinear optics (NLO); they display saturable (SA) and ... -
Allenylporphyrins: a new motif on the porphyrin periphery
SENGE, MATHIAS (2009)Palladium-catalysed Suzuki?Miyaura cross-coupling proved to be the simplest and most efficient method for attaching an unsubstituted allene, a novel substituent and potential functional group, to the porphyrin periphery. ... -
Anthracenylporphyrins
SENGE, MATHIAS (2010)We report the synthesis and characterization of meso-anthracenylporphyrins with zinc and nickel metal centers. A variety of novel aryl and alky meso substituted anthracenylporphyrins were synthesized via step-wise Suzuki ... -
