Outline of Annual Research Achievements

The Fellow has prepared two classes of secondary building unit (SBU) to develop as porous porphyrin solids for singlet oxygen generation. First, a classic metal-organic framework with zirconium acetate linkages, second, porous polymers from a highly reactive unit which will be used to make a large family of porous polymers. Surface area measurements have revealed the important parameters for the preparation of porous materials from these units. Singlet oxygen generation studies have shown that the building units exhibit SO quantum yields close to unity. The Fellow has undertaken a literature review of the subject in order to complete a review paper.

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

Many different types of compound and connection have been attempted especially for the preparation of porous polymers (and MOFs) based on porphyrinic compounds. The Fellow has now identified the two classes of compounds on which to focus. Also, it has been established that the components of these materials have large singlet oxygen generating capacities. The Fellow has worked hard to identify the compounds and has taken advice from coworkers around him in the laboratory and from his supervisor.

Strategy for Future Research Activity

Now that the basic unit materials of the project have been prepared/identified (including novel building units), the project will proceed more easily. Current porous materials will be tested for singlet oxygen generation (and other properties).Fuyrther materials will be prepared based on the identified building units and the physical and chemical properties tested. The Fellow will complete a review paper for publication. Preliminary results on singlet oxygen generation will be published.
