A further extension of this system consists in the inclusion of spiro components and appears particularly advantageous in the case of multilayered
polyspiro systems of the following type:

3.15( 1,4 ),6( 1 ,4,2,5),9( 1 ,2,5,4), 12( 1 ,5,2,4)-pentabenzenatrispiro [5.2.2.6 12 .3 9 .2 6 ] triocosaphane
To close this chapter and in anticipation of subsequent discussions it
should be kept in mind that the new assembly names obtained along the
lines of phane nomenclature can now be used as parent names for the
multifarious ways of substitution by functional groups in the same way as
the more conventional parent names of old.
