Novel syn- and anti-[2.n](3,9)phenanthrenophanes (n=3,4) were successfully prepared by the intramolecular [2+2] photocycloaddition of α,ω-bis(3-vinyl-9-phenanthryl)alkanes. The anti-isomer of n=3 was found to give excimer fluorescence in spite of the only

(Chemical Equation Presented) Novel photostable oxa[3.n](3,9)- and [3.3](3,10)phenanthrenophanes (n = 3, 4) bearing trimethylene-type linkage(s) were successfully synthesized by the intramolecular acid-catalyzed etherification of the corresponding precursor diols. syn-Oxa[3.3](3,10) phenanthrenophane afforded the most red-shifted excimer fluorescence (λmax = 432 nm) among the phenanthrenophanes so far prepared.
