PERTOSYLATED POLYAZA[N](9,10)ANTHRACENOPHANES

Pertosylated polyaza[n](9,10)antracenophanes have been obtained in hig h yields by a modification of the Richman-Atkins methodology. Molecula r Mechanics calculations as well as the crystal structure of the N,N', N '',N triple ratosyl-2,6,9,13-tetraaza[14](9,10)anthracenophane 4 der ivative reveal the existence of a well defined cavity where both the a romatic moiety and the nitrogen donor atoms converge. Reduced mobility of the aliphatic chain is also observed as well as the presence of so me strain at the benzylic positions. (C) 1997, Elsevier Science Ltd.
