Abstract
Series of biphenyl as well as cholesterol derivatives with nitroxide radicals have been prepared to investigate their magnetic/liquid crystalline characters. Weak antiferromagnetic interactions in the low temperature region with no liquid crystalline character have been observed in all cholesterol and several biphenyl derivatives prepared while a cyanobiphenyl derivative with TEMPO substituent have been found to show ferromagnetic interactions in the low temperature region on the one hand and smectic liquid crystalline behavior at elevated temperatures on the other hand.
