text: Yo, check it out, I got some science to drop
  A series of seven dyad molecules, non-stop
  Using that [Ru(tpy)(NN)I] catalyst type
  (NN = 2,5-di(pyrid-2'-yl) pyrazine), right?
  
  We got three options for the NN group, listen close
  2,5-di-(1',8'-dinaphthyrid-2'-yl) pyrazine, that's dope
  Or 4,6-di-(1',8'-dinaphthyrid-2'-yl) pyrimidine, straight fire
  Bridging ligand got bipyridine or phenanthroline desire
  
  These dinuclear complexes, we gotta analyze
  (1)H NMR spectra, electronegative iodide, no lies
  Crystal X-ray analysis for complex 10a, that's real
  Electronic absorption spectra, let's see how they feel
  
  Emission properties for the sensitizers, we'll report
  Oxidation and reduction potentials we'll sort
  Excited state redox properties, we calculate
  Gotta know the science, no room for debate
  
  Turnover numbers, initial rates, induction periods too
  Oxygen production with a blue LED, that's what we do
  Sodium persulfate, our sacrificial oxidant, no doubt
  We run experiments, with and without irradiation, check it out
  
  Dyad performance, it's all about the potential gap
  Between excited state reduction and ground state water oxidation, that's a rap
  The most active system got 5,6-dibromophen as the auxiliary
  And the least active system got 4,4'-dimethylbpy, it's secondary
