Hello, everybody.
Lets say i have two linear molecules (its geometry) parallel to each other. Both have n atoms. Is there some kind of reaction or is there some way to make these molecules acquire a helical shape, like DNA? I ask this because i was curious with the helical shape of DNA and was wondering if it is possible to do it in an artificial way and with molecules?

If the answer is yes, how is this done?

Thank you.

I believe some forms of polythiophene with bulky substituents adopt a helical shape.  I also believe it's possible to bind oligomers and polymers onto carbon nanotubes in helical fashion.  There are probably other examples out there.  Try a google search and see what you come up with.
