Correction: Highly photoluminescent copper carbene complexes based on prompt rather than delayed fluorescence

Abstract

Correction for ‘Highly photoluminescent copper carbene complexes based on prompt rather than delayed fluorescence’ by Alexander S. Romanov et al., Chem. Commun., 2016, 52, 6379–6382.

The original article reported photoluminescence data on cyclic (alkyl)(amino)carbene complexes of copper and gold halides 1a–c and 2a–c based on time-correlated single photon counting (TCSPC) measurements carried out over a 10–60 nanosecond timescale which at the time were interpreted as evidence for prompt fluorescence. The authors have remeasured these complexes and this has shown that fluorescence is not the major emission pathway. Given the lifetimes in the microsecond range, the major emission pathway is consistent with phosphorescence. Using either a 370 nm nano-LED or operating in the phosphorimeter mode (with an F1-1029 lifetime emission PMT assembly, using a 450 W Xe lamp with λ_ex 370 nm, and a decay window of 160–200 μs) gave the lifetimes τ as shown in Table 1.
