A Thermodynamic Model Self-Assembly of Zinc Porphyrin Complexes

2 A Thermodynamic Model Self-Assembly of Zinc Porphyrin Complexes 

The equilibrium constant for the self-assembly of the cyclic oligomer containing n monomer units. 

The equilibrium constant for the open (noncyclic) association of a monomer with a growing linear oligomer containing n-l monomer units. This is a difficult parameter to measure because strictly 

The effective molarity is a very useful parameter that represents the concentration at which polymer formation begins to compete with the self-assembly of closed oligomers, i.e. it is the upper limit at which the cyclic structure is stable. 

Critical self-assembly concentration, csac = [monomer], when---------= 1
