【 摘 要 】
After reviewing the new physics and chemistry in high electrostatic fields we use density functional theory to show that in fields around 1.5 V/Å the bandgap of polythiophene reduces to zero leading to field-induced metallization. In poly(ethylene glycol), on the other hand, such fields lead to giant electrostriction of over 20% in length. Lastly, we give two examples of field-induced polymerization: (1) the closure of sulfur molecules Sn at n = 8 is suppressed remaining linear up to n ∼ 20. (2) This also happens to water which forms linear whiskers up to n ∼ 11.
