摘要:New two-photon up-conversion fluorescence (TPF) sensors, containing triphenylamine or carbazole as donor (D) and flanked pyridinylbenzothiadiazole as acceptor (A) to form D-pi-A(n) ((n-1, 2 or 3)) architecture, were synthesized and characterized. The investigation correlated molecular structure (acceptor number) with linear absorption, one-photon fluorescence (OPF) and two-photon fluorescence (TPF) detecting Cu2+, Ni2+, Hg2+ and Ag+ was carried out. Sensors containing more acceptor groups were found to exhibit greater sensitivity to both absorption and fluorescence detection. A comparison between OPF and TPF responses to the given metal ion (Cu2+) showed that the sensitivity of TPF quenching is larger than that of OPF quenching. This strongly supports the idea that pyridinylbenzothiadiazole-based chromophores with more acceptor groups possess potential application as two-photon up-conversion sensors. (C) 2013 Elsevier Ltd.
