Organisation and ordering of 1D porphyrin polymers synthesised by on-surface Glaser coupling
Saywell, Alex
Description:
One-dimensional polymer chains consisting of π-conjugated porphyrin units are formed via Glaser coupling on a Ag(111) surface. Scanning probe microscopy reveals the covalent structure of the products and their ordering. The conformational flexibility within the chains is investigated via a comparison of room temperature and cryogenic measurements.
