WebUsing a metal templating strategy, 5,15-porphodimethene metal complexes were synthesized and their structure confirmed by single crystal X-ray analysis. The anagostic interaction causes distortion, while the hydrogen bonding interactions generate dimerisation and array formation in these complexes. WebAug 20, 2012 · The four porphodimethene isomers, 5,10- and 5,15-disubstituted, have been synthesized in a one-pot reaction by the Lindsey protocol. Three of them have been characterized by X-ray crystallography. Structures show that two of them are 5,15-porphodimethenes: one is syn-equatorial, another is anti-configuration; the third one is … piantballshop in berlin
