摘要: Abstract Phenanthro[3,4-c]fluorenone ( 5 ) and phenanthro[3,4-c]fluorene 1 have been prepared from hexahelicene-5,6-quinone. The effect of the presence a five-membered ring on helical conformation has studied by comparison NMR data with those hexahelicene. Force field calculations structure agree results analysis.
