In conclusion, chiral cyclic [n] was induced by multiple (≧ 3) chromophores (bifluorenyl units). The even-odd effect of the number of units in matching of the sign of the orbitals was indicated by DFT calculations. In the case of an odd number, the symmetry of the HOMO in bifluorenyl unit forbids making the orbital signs around all of spirocarbons match, in contrast to the case of an even number.
