Abstract:We report a series of dibenzyl isophthalates (DBIs) as versatile hosts for room-temperature phosphorescence (RTP) systems, leading to host-guest systems with quantum yields (QY) of up to 77 % or lifetimes of up to 21.0 s for the guest coronene d12. Furthermore, a 4,4’-Br substituted DBI was used to form host-guest RTP systems with 15 different aromatic guest molecules, to tune the phosphorescence emission color from blue to red and to demonstrate the versatility of the host. Mechanistic insights were gained th… Show more
