2,5-Diformylbenzene-1,4-diol (5) is a well-suited starting compound for the preparation of ditopic hydroquinone-based ligands. Here, we report an optimized synthesis of 5 which improves the overall yield from published 7 % to 42 %. Three new ditopic Schiff base ligands, 2,5-[iPr2N(CH 2)2N=CH]2-1,4-(OH)2-C 6H2 (8), 2,5-(pyCH2N=CH)2-1,4-(OH) 2-C6H2 (9), and 2,5-[py(CH2) 2N=CH]2-1,4-(OH)2-C6H2 (10), have been synthesized from 5 and structurally characterized by X-ray crystal structure analysis (py = 2-pyridyl).

A large variation of the nonlinear transmission properties of a cyclen-based bis(styryl)benzene can be induced by a small change of the linear absorption spectrum upon Zn2+ binding. This result has been interpreted in the frame of a sequential
