So far, I've tried to find why cis-polyethyne does not conduct electricity whilst trans-polyethyne does. I've got no satisfactory answer until now, unfortunately.
For example, I found this on wikipedia:
Conjugated system - Wikipedia, the free encyclopedia
But it doesn't tell me why cis doesn't conduct while trans does...
I've seen this answer on a forum I got through a Google search.
While this may be true, I have found nothing to confirm this... any idea?Quote:
the trans isomer will have (relatively) straight chains and can align alongside one another allowing some degree of crosslinking and overlapping of the delocalised electrons.
The cis-isomer contains 'kinks' (yah Ray Davies rocks) preventing good alignment.
Thanks!
