Using acyclic diene metathesis (ADMET) polymerization, we have synthesized a series of random conjugated copolymers from diene monomers based on tetraphenylethene (TPE), which is an aggregation-induced emission (AIE)-active mol., and comonomers such as 1,9-decadiene, 2,7-divinyl-9,9-di-n-octylfluorene, and 1,4-dihexyl-2,5-divinylbenzene. These all-hydrocarbon copolymers exhibit good solubility and high mol. weights As proved by 1H NMR spectra, chain segments composed of two monomers are randomly distributed in the polymers. Absorption and emission features from both TPE units and those conventional diene segments in conjugated copolymers are observed in their optical spectra. Because of the presence of AIE-active TPE units, emission intensities of the copolymers are greatly enhanced in tetrahydrofuran/water mixtures with increased water content. Moreover, the fluorescence of ADMET polymers can be quenched by palladium ions in quasi-aqueous solutions following a dynamic quenching mechanism. The fluorescence quench degrees are affected by both chem. structures of the copolymers and the solvent polarity. Our findings demonstrate that ADMET conjugated polymers have enormous potential as fluorescent “”turn-off”” probes specific for palladium ions even in the absence of a particular coordination interaction.

Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is a ruthenium-based olefin metathesis catalyst. It is useful for olefin cross metathesis (CM) and ring closing metathesis (RCM) of terminal olefins under a variety of reactions conditions, and so on.Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium
