  1. Crosslink porphyrin films
  2. Run AA using film adsorption
  3. Prepare next highest porphyrin concentration solution. Then add salts to these higher porphyrin solutions
  4. Run UV-vis on film adsorption and porphyrin-salt solutions


  • The general protocol for porphyrin film crosslinking described on 2012/09/14 was followed for the films listed below

Films Crosslinked:

  1. PVOH(22K) 1.0073g+1.0mL GA+1mL porphyrin
  2. PVOH(22K) 1.05225g+1.0mL GA+1mL porphyrin

Crosslinking information
