Size-controlled synthesis of conjugated polymer nanoparticles in confined nanoreactors

Soluble conjugated polymeric nanoparticles are synthesized by Suzuki-type polycondensation of two monomers (Ax + By, x>2, y≥2) in the channel of ordered mesoporous silica-supported carbon nano-membranes (nanoreactors). These synthesized soluble conjugated microporous polymers (SCMPs) exhibit uniform particle-size distributions and well-controlled particle sizes. The control of particle size stems from the fact that the polycondensations exclusively take place inside the mesochannels of the nano-reactors. Photo-luminescence studies show that polymeric nanoparticles with tetraphenylethene and pyrene substructures are highly fluorescent. The combination of both physical stability and process-ability offered by the soluble polymeric nanoparticles makes them particularly attractive in light emitting and other optoelectronic applications.

Micropatterning of metallopolymers: Syntheses of back-to-back coupled octylated 2,6-Bis(pyrazolyl)pyridine ligands and their solution-processable coordination polymers

This paper presents a 10-step synthetic route for the preparation of a series of new back-to-back coupled 2,6-bis(pyrazol-1-yl)pyridine (bpp) ligands (L0-L3) decorated with tetraoctyl chains. Ligand L1 self-assembles with Zn 2+ ion to form a highly soluble metallo-supramolecular polymer 1 with Mn ～ 9600 g/mol. To demonstrate the processability of polymer 1, by following a "top-down" approach periodic one-dimensional fluorescent microstripes were fabricated on a silica substrate.

Organic field-effect transistors based on novel organic semiconductors containing diazaboroles

New π-conjugated systems containing a diazaborole unit have been prepared by the reaction of the corresponding boronic acids with diamines. They are nearly colorless compounds with electron-donating properties. Single crystal X-ray structure analysis of t
