The paper describes the synthesis of several polypyromellitimide samples containing phosphine oxide in the backbone and maleimido groups as pendant side chains. These polymers were obtained by solution polycondensation reaction in DMF in three steps. First step involved the reaction of equimolar amo

The previously reported reaction of phthalocyanines [H 2 (pc)] 5-8. The corresponding dihydroxyphosphorus(V) phthalocyanine hydroxides 9-12 have also been synthesized for the with PBr 3 , which was claimed to give a phosphorus(III) phthalocyanine "(PcP III )", has been reinvestigated in detail first
## Abstract H,H and P,H coupling constants and variableβtemperature ^1^H and ^13^C NMR spectra and ^13^C __T__~1~ values for some macrocyclic dithiophosphonic esters are presented to show that these compounds possess reduced flexibility in comparison with crown ethers. The NMR spectroscopic results
