Zethrene derivatives substituted by phenylethynyl groups bearing electron-donating and/or accepting groups were synthesised by iodine-induced transannular cyclisation of dehydrodinaphtho[10]annulene as the pivotal step followed by Sonogashira coupling reaction. Their physical properties were investigated to elucidate the effects of the substituents on the… CONTINUE READING
