TL;DR: Experimental results suggest that it is feasible to alter the type of excimer formed by anthracene units attached to the PAMAM dendrimers through altering the propensity for ground-state aggregation, and increased pi conjugation in the molecular framework of anthracenes-substituted PAMam d endrimers leads to intense and exclusive excimer emission from Anthracene at room temperature.

TL;DR: In this article, the synthesis and characterization of unmodified graphene oxide quantum dots (GOQDs) with white-light-emitting properties, upon photoexcitation at 340 nm, was reported.

TL;DR: The mechanism derived from rate studies shows that HMPA is important not only in increasing the reduction potential of Sm(II) but also in enhancing the inherent reactivity of the radical anion intermediate formed after electron transfer through conversion of a sterically congested contact ion pair to a solvent-separated ion pair.

TL;DR: The analysis of the luminescence spectra in protic solvents suggests that hydrogen bonding plays a crucial role in regulating the photophysical characteristics of the system.

TL;DR: The free energy dependence of electron transfer in a few small-molecule donor--acceptor systems having hydrogen-bonding appendages was studied and it was observed that the rate depends very feebly on distance, but distance dependence studies did not confirm the prediction of enhanced rates at larger distances in the inverted region.
