text: Yo, check it out, here's the deal
  We got a proton conducting composite that's real
  Impregnated EMIMCl ionic liquid, no doubt
  In the mesoporous MIL-101(Cr)-SO<sub>3</sub>H MOF, we sprout
  
  This EMIMCl@MIL-101(Cr)-SO<sub>3</sub>H composite is straight fire
  Thermal and chemical stability it won't tire
  EMIMCl stays put even at 500 K heat
  And even in moist conditions, it's hard to beat
  
  Listen up, this composite got skills
  Proton conductivity, it truly fulfills
  Anhydrous state, at <i>&#963;</i><sub>473 K</sub> it goes
  1.5 &#215; 10<sup>-3</sup> S cm<sup>-S</sup>, that's how it flows
  
  But that's not all, humidity ain't a threat
  At <i>&#963;</i><sub>(343 K/60%-80%RH)</sub>, it's still a bet
  0.10 S cm<sup>-1</sup> or higher, it can't be denied
  EMIMCl@MIL-101(Cr)-SO<sub>3</sub>H, it's got that stride
  
  So remember this name, it's a solid state conductor
  For PEMFC applications, it's a game changer
  EMIMCl@MIL-101(Cr)-SO<sub>3</sub>H, the one you desire
  Ready to deliver, set the world on fire
