When ether vapor was allowed to diffuse into a CH ( 2 ) Cl ( 2 ) solution of an enantiomer of a hexa - peri - hexabenzocoronene ( HBC ) derivative carrying a chiral ( BINAP ) Pt ( II ) - appended coordination metallacycle ( HBC ( Py ) ( [ ( R ) - Pt ] ) or HBC ( Py ) ( [ ( S ) - Pt ] ) ) , screw - sense - selective assembly took place to give optically active nanotubes ( NT ( Py ) ( [ ( R ) - Pt ] ) or NT ( Py ) ( [ ( S ) - Pt ] ) ) with helical chirality , which were enriched in either left - handed ( M ) - NT ( Py ) ( [ ( R ) - Pt ] ) or right - handed ( P ) - NT ( Py ) ( [ ( S ) - Pt ] ) , depending on the absolute configuration of the ( BINAP ) Pt ( II ) pendant .
