[2.2]Paracyclophane-1,9-dienes substituted with n-octyl chains have been synthesised from the corresponding dithia[3.3]paracyclophanes using a benzyne induced Stevens rearrangement. The use of 2-(trimethylsilyl)phenyl trifluoromethanesulfonate and tetra-n-butylammonium fluoride as in situ source gave significantly improved yields over traditional sources enabled preparation [2.2]paracyclophane-1,9-dienes on multi-gram scale.
Poly(p-phenylenevinylene)s (PPVs) with single reactive end groups have been prepared high molecular weights, narrow polydispersities (ĐM) and excellent functionality (f). PPVs functionalised α-bromoester are effective macroinitiators in the atom transfer radical polymerisation (ATRP) of methyl methacrylate (MMA).
The ring opening metathesis polymerisation (ROMP) of three <italic>n</italic>-octyl substituted [2.2]paracyclophane-1,9-dienes, initiated by Grubbs ruthenium carbene complexes is reported.
Ring expansion metathesis polymerisation (REMP) has proven to be a viable approach prepare high purity macrocyclic phenylenevinylene polymers.
This paper discusses the living nature of ring opening metathesis polymerisation (ROMP) alkoxy and alkyl substituted [2.2] paracyclophane-1,9-dienes (<bold>M1</bold> <bold>M2</bold>), initiated with Grubbs’ second third generation catalysts (<bold>G2</bold> <bold>G3</bold>).
Dialkoxy and dialkyl substituted paracyclophane-1,9-dienes undergo bidirectional ring opening metathesis polymerisation (ROMP) on addition of bifunctional Hoveyda–Grubbs initiators.
Conjugated polymer nanoparticles (CPNs) can be synthesized by a Suzuki-Miyaura cross-coupling miniemulsion polymerization to give stable dispersions with high concentration of uniform nanoparticles. However, large amounts added surfactants are required stabilize the and prevent aggregation Removal excess surfactant is challenging, residual in thin films deposited from these reduce performance optoelectronic devices. We report novel approach prepare no using fluorene monomer,...
Selectively main chain 13C-labeled poly(p-phenylenevinylene)s (PPVs) were synthesized by ring-opening metathesis polymerization (ROMP) of dialkoxy-substituted [2,2] paracyclophane-1,9-dienes (M) using the Grubbs second generation ruthenium carbene complex (G2). Analysis natural abundance and PPVs NMR spectroscopy showed no structural defects for these polymers. Comparison in situ 1H 13C during ROMP labeled unlabeled monomer enabled active ends present initiation propagation reaction to be...
