We have taken the advantage of this TICT behavior for the design of new fluoroionophores and synthesized a series of trans-4-(N-arylamino)stilbenes containing a hydrazone substituent, namely 1Hz、2Hz and 3Hz. According to literatures, the hydrazone and methoxyl groups can selectively interact with Cu2+ ion.
