Abstract
Polycatenar saturated macrocycles 1,10-bis[3,4,5-tris(4-dodecyloxy)benzoyl]-1,10-diaza-4,7,13,16-tetrathiacyclo-octadecane (3b) and 1,10-bis[3,4-bis(4-dodecyloxy)benzoyl]-1,10-diaza-4,7,13,16-tetrathiacyclo-octadecane (3d) reacted with [Pd(MeCN)(4)][BF4](2) led to the cationic complexes [4b][BF4](2) and [4d][BF4](2), respectively. Complexes [4b][BF4](2) and [4d][BF4](2) showed smectic mesomorphism on heating as confirmed by small angle X-ray diffraction. A concurrent, irreversible structural change of the complex cations was observed and a tentative explanation is suggested.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
