View source for Highly polycyclic small molecule

{{stub}}

This page is about small molecules that feature a lot of polycyclic elements. <br>
Polycycles not just in in 2D but also (and perhaps predominately so) in 3D. <br>
Preferably with no free rotational degrees of freedom in  the molecule.

Such molecules may eventual provide a way out of the <br>
[[fat finger problem]] vs [[floppy finger problem]] dilemma <br>
that one faces with natural proteins.

'''Highly polycyclic small molecule could be integrated as an artificial side-chain in synthetic peptides.'''<br>
For integration of different technologies see page: <br>
[[Combining advantages of different selfassembly technologies]]

== Examples ==

[[Spiroligomers]]
* 2D polycyclic
* no rotational degrees of freedom

----

Molecules close to adamantane in structure. These are close in nature to diamond.
One proposal are adamantanes with corners substituted with boron sand or nitrogen.
* Either alternatingly wit four nitrigens and 4 borons
* Or all the same either all 8 substituted with nitrogen (adamanzane) or all 8 substituted with boron.

== Misc ==

Aromatic polycyclic compounds are also often optically active
and potentially of interest as basis for [[optically activated nanoscale actuators]].
