Objective

Description

Part 1

  • Porphyrin film which was cross-linked on 19/10/2012 was placed in to a 1% HCL solution with a volume of 100mL.

Part 2: Prepare a porphyrin solution of 50micM

Part 3: UV-Vis

  • Combination of 1 ml of salt/acid (50micM), 1 ml of 50 micM of porphyrin and 2 ml of HPLC water.

Data

Before placing porphyrin film in to 1 % HCl solution


Right after placing porphyrin film into 1 % HCl solution

  • Edges of the film become more green.

48 hours after placing porphyrin film, prepared into 1 % HCl solution

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

Notes

This area is for any observations or conclusions that you would like to note.


Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized.
