A macrocycle-appended naphthalimide derivative and its Eu(III) complex show triple luminescence from isolated naphthalimide (blue), aggregated naphthalimide excimers (green) and Eu centres (red) with the balance being sensitive to the degree of aggregation, allowing white light emission to be obtained from a single molecule. 
New heterometallic Ir(III)2-Eu(III) complexes: white light emission from a single molecule.
The design of a relatively simple bifunctional ligand led to the obtainment of three new Ir( III)2-Eu(III) heterometallic complexes that allow tuning of the photophysical properties and pure white light emission from a single complex. Expand

Molecular flexibility tuned emission in "V" shaped naphthalimides: Hg(II) detection and aggregation-induced emission enhancement (AIEE).
Four "V" shaped 1,8-naphthalimides have been synthesized and their fluorescence quantum-yields correlated to their molecular flexibility, and Hg(II) was found to be an AIE active molecule with the formation of fluorescent nanoaggregates. Expand
White-light emission from discrete heterometallic lanthanide-directed self-assembled complexes in solution† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c7sc00739f Click here for additional data file.
It is demonstrated that fine tuning of the lanthanide ions molar ratio in the self-assemblies combined with the intrinsic blue fluorescence of the ligand allows for the successful emission of pure white light with CIE coordinates of (0.33, 0.34). Expand

d → f energy transfer in a series of Ir(III)/Eu(III) dyads: energy-transfer mechanisms and white-light emission.
Calculations based on consideration of spectroscopic overlap integrals rule out any significant contribution from Förster energy transfer over the distances involved but indicate that Dexter-type (exchange) energy transfer is possible if there is a small electronic coupling that would arise, in part, through π stacking between components.
