Abstract
The emission transition dipole moments of single-molecule free-base phthalocyanines at an air/glass interface were visualized using defocused wide-field fluorescence microscopy at a temporal resolution of 100-200 ms. Isolated molecules showed slow proton tautomerization, which is consistent with previous theoretical calculations in the gas phase, which predicted large activation energies.

Summary
(B100 s) compared with the rate of tautomerization. In this study, we report the real-time visualization of the ETDMs of single H2Pcs using defocused wide-field microscopy at a temporal resolution of 100 ms.[18,19,20,21,22,23] We found that a H2Pc derivative shows slow tautomerization at an air/octadecyl-group-modified glass interface, which is consistent with previous DFT calculations.
