芘发色团表现出可逆的能量转移到铕离子，导致氧依赖的镧系发光。两种不同的途径可以引起氧依赖性：在T-1态和发射态之间的快速可逆能量转移，或在三重态淬灭的时间尺度上的缓慢T-1-D-5（0）能量转移。
Pyrene chromophores are shown to exhibit reversible energy transfer to europium ions, resulting in oxygen dependent lanthanide luminescence. Two different pathways can give rise to oxygen dependence: rapid reversible energy transfer between the T-1 state and the emissive state, or slow T-1-D-5(0) energy transfer on the timescale of triplet state quenching.
