TL;DR: Empirical correlations were observed among the hydrogen-bonding strength, ESIPT kinetics, and thermodynamics, demonstrating a trend that the stronger N-H···N hydrogen bond leads to a faster ESIPt, as experimentally observed, and a more exergonic reaction thermodynamics.

TL;DR: Time-resolved kinetics lead us to conclude that CT excited states relax to a ground-state intermediate with a time constant of ~3 µs, followed by a structural relaxation to the original CN-Cz2:PO-T2T configuration within ~14 ²s.

TL;DR: Compared with their unlocked counterparts, a substantial increase in the emission yield is also observed for p-LHBDI and H2BDI in anionic forms in water, and accordingly the structure versus luminescence relationship is fully discussed based on their chemistry and spectroscopy aspect.

TL;DR: Facile derivation of 10-aminobenzo[h]quinoline via replacing one of the N-H hydrogen atoms by various substituents generates a new series of excited-state intramolecular N- H proton-transfer molecules, which can be widely tuned from 590 nm to 770 nm simply by harnessing the electron-donating/withdrawing strength of the substituent.

TL;DR: A new series of molecules, T1-T4, possessing thermally activated delayed fluorescence (TADF) have been strategically designed and synthesized and two types of structural arrangement are proposed that give distinct emission properties, one with and the other without TADF.
