Photoluminescence quantum yields (PLQYs) and single crystal X-ray structures of 100 reported compounds were assembled, %V-bur of the ligand systems were calculated and analyzed for correlations. We found that increased shielding of the central Cu(I) cation relying on shared contributions of both (NN) and (PP) ligand systems led to increased PLQYs. These findings are of relevance for future characterizations of Cu(I)-based complexes and their photophysical behavior in the solid-state.Biochemistry & Molecular BiologyChemistry, MultidisciplinaryBiochemistry & Molecular BiologyChemistrycopper(i)photoluminescence quantum yieldcrystal structurepercent volume buried (%v-bur)empirical correlationsemitting electrochemical-cellsheteroleptic cu(i) complexesphotophysical propertiessteric propertiesligandsphotoluminescenceluminescencediphosphinephosphinetext::journal::journal article::research article
