Presentation Transcript

  1. Example of an application for electronic spectroscopy in coordination compounds: Solar Energy Conversion

  2. See Grätzel et al. J. Am. Chem. Soc. 2001, 123, 1613

  3. Synthesis of (dbbpy)Pt(dmid) (dbbpy)Pt(dmid)

  4. (dbbpy)Pt(dmid) P-1 R1 = 0.03 dbbpy groups have empty p* orbitals ==> Strong MLCT absorptions

  5. (dbbpy)Pt(dmid) (dbbpy)Pt(dmid) + TCNQ [(dbbpy)Pt(dmid)][TCNQ]

  6. [(dbbpy)Pt(dmid)]2[TCNQ] 3.50 3.76 3.54 Presence of TCNQ reduces Pt-Pt distances and changes the electronic structure ==> Stronger CT absorptions

  7. Re2Cl4(dppm)2TCNQ Packing Diagram

  8. TCNQ Cplxs.: • Very strong CT absorptions • Lower energy Only d-d transitions (very weak)
