Due to their crystalline perfection and due to the morphological control, organic nanofibers are perfectly suited for fundamental studies of optics, mechanics, and electronics on the mesoscale. HorstGnther Rubahn tells Nanowerk.The result is an organic molecular nanotechnology that allows for the generation of mutually aligned, morphologically welldefined lightemitting organic nanofibers from functionalized molecules, essentially bridging the gap between the nanoscopic and microscopic worlds.

Assembling nanoscopic components into macroscopic materials is an appealing goal but one of the enormous difficulties lies in bridging approximately six orders of magnitude that separate the nanoscale from the macroscopic world.

New research results coming out of Denmark offer the basis for novel organicmoleculebased nanotechnological concept that allows for the generation of mutually aligned, morphologically welldefined lightemitting organic nanofibers from functionalized molecules, essentially bridging the gap between the nanoscopic and microscopic worlds. Assembling nanoscopic components into macroscopic materials is an appealing goal but one of the enormous difficulties lies in bridging approximately six orders of magnitude that separate the nanoscale from the macroscopic world. An obvious direct approach to molecular nanotechnology therefore is to start with organic molecules as building blocks.

We are long way from realizing this vision but researchers are busily laying the foundation for nanoscale engineering. Our nanofibers can be transferred easily and destructionfree as individual entities or in massive parallel fashion onto prestructured target substrates. An obvious direct approach to molecular nanotechnology therefore is to start with organic molecules as building blocks. Nanowerk Spotlight The vision of revolutionary bottomup nanotechnology is based on concept of molecular assembly technologies where nanoscale materials and structures selfassemble to microscale structures and finally to macroscopic devices and products. Applications as passive and active elements in printed alloptical chips are within reach.

Applications as passive and active elements in printed alloptical chips are within reach.Work in our group has allowed us to overcome the previous obstacles of growing molecular nanowires namely the controlled growth of crystallites of predefined shapes and predefined mutual orientations and their transfer onto more complicated target substrates Dr.
