TLDR
The magnetic properties of poly(phenylacetylene)s with radical groups at the para position, poly[(3,5-di-tert-butyl-4-oxyphenyl)acetylene] (1), poly[4]-(3.5)-di-TERT-Butyl 4-oxymethyloxyamino)phenyl]acetylene [2] (2), and poly[[4]-Ntert]-butyl N-oxy amino [3] (3]-acetylene as mentioned in this paper were studied with a SQUIDAbstract:
The magnetic properties of poly(phenylacetylene)s with radical groups at the para position, poly[(3,5-di-tert-butyl-4-oxyphenyl)acetylene] (1), poly[[4-[(3,5-di-tert-butyl-4-oxyphenyl)(3,5-di-tert-butyl-4-oxocyclohexa-2,5-dien-1-ylidene)methyl]phenyl]acetylene] (2), and poly[[4-(N-tert-butyl-N-oxyamino)phenyl]acetylene] (3), were studied with a SQUID magnetometer. The magnetization and magnetic susceptibility indicated unexpected antiferromagnetic interactions between the radical sites. The exchange interaction observed in these conjugated polyradicals was discussed in connection with their computationally modeled structuresread more
