Abstract:

Two novel D-π-A type terpyridine derivatives with two-photon properties were synthesized using 2,2'∶6',2″-terpyridine as the acceptor(A) and other functional groups as the donor(D). For the two D-π-A type terpyridine derivatives, their linear absorption, single- and two-photon properties were measured. These results show that the target compounds have good fluorescence with the fluorescence quantum yield(Ф)up to 0.45 and the maximal two-photon absorption cross section(δ2) up to 406 GM at 830 nm. Theoretical calculations were consistent with the experimental results.

Key words: Terpyridine derivative, Optical property, Single-photon fluorescence, Two-photon fluorescence
