Coordination self-assembly of a series of tetranuclear Pt(ii) macrocycles containing an organometallic backbone incorporating ethynyl functionality is presented. The 1 : 1 combination of a linear acceptor 1,4-bis[trans-Pt(PEt(3))(2)(NO(3))(ethynyl)]benzene () with three different dipyridyl donor 'clips' () afforded three [2 + 2] self-assembled Pt(II)(4) macrocycles () in quantitative yields, respectively [ = 1,3-bis(3-pyridyl)isothalamide; = 1,3-bis(3-pyridyl)ethynylbenzene; = 1,8-bis(4-pyridyl)ethynylanthracene]. These macrocycles were characterized by multinuclear NMR ((1)H and (31)P); ESI-MS spectroscopy and the molecular structures of and were established by single crystal X-ray diffraction analysis. These macrocycles () are fluorescent in nature. The amide functionalized macrocycle is used as a receptor to check the binding affinity of aliphatic acyclic dicarboxylic acids. Such binding affinity is examined using fluorescence and UV-Vis spectroscopic methods. A solution state fluorescence study showed that macrocycle selectively binds (K(SV) = 1.4 × 10(4) M(-1)) maleic acid by subsequent enhancement in emission intensity. Other aliphatic dicarboxylic acids such as fumaric, succinic, adipic, mesaconic and itaconic acids caused no change in the emission spectra; thereby demonstrating its potential use as a macrocyclic receptor in distinction of maleic acid from other aliphatic dicarboxylic acids. |
