Objective

Description

Part 1

  • Place the porphyrin film (with 2 drops of HCL), prepared on 24/10/2012, into a 6 molality of NaCl with 100ml of HPLC water.
  • Place the NaCl solution in to a hot plate and wait until temperature raises to 70C.
  • At 70C place the film into beaker.

Data

48 hours After placing porphyrin film into 1 % HCl solution

  • The film became full green.(compared to the pictures on 31/10/2012)

Porphyrin film with 2 drops of HCL, prepared on 24/10/2012

  • Before cross-linking
  • The film shrunk and look more brittle.
  • More intense green color.
