Parallel with the addition of RB into the suspension of PRBT or PSBT in MeOH, the PL intensity at 522 nm which originated from chiral POPs gradually decreased along with the elevated emission at 594 nm from RB (Figure and). The CIE color coordinates of PRBT had gradually shifted from (0.28, 0.51) for pure PRBT to (0.54, 0.40) for their complex (PRBT/RB = 1/10) (Figure and S48). Luminescent decay curves had indicated that the lifetime of PRBT had decreased from 0.72 ns in absence of RB to 0.52 ns after addition of 100 uM RB into the mixture (Figure and). This lifetime decrease had supported the energy transfer process from chiral POPs as donors to RB as acceptor.
