Control Regime

A new series of ESIPT molecules has been investigated. We found that these compounds undergo kinetic-control ESIPT and the reaction barriers along proton transfer coordinate can be finetuned by different substitution on amino group.

The electronic density redistributes and it migrates in opposite directions for HBO when compared to those of 5A-HBO and 6A-HBO. The amino group in the HBO framework can change the behavior of the intramolecular hydrogen bonds.

The color of ESIPT luminescence of HPIP is tuned in a wide range by the introduction of aryl group(s), and thus a series of PIPs showing blue to red emission is realized.
