We develop a procedure to design complex tubular branched tangle structures based on curved and branched carbon nanotubes (CNTs). A curved CNT is obtained by mitering CNT segments, and a branched CNT can be generated by puncturing a generic fullerene in line with its specific symmetry. With curved and branched CNTs as basic building blocks, we can construct a wide range of hypothetical molecular structures with arbitrary space curves based on CNTs. Following the procedures given above, we show CNT versions of Bathsheba Grossman’s Metatron and Metatrino sculptures and present the corresponding beaded model of Metatrino.
