Preparation of Fluorescent Conjugated Polymer Films with Different Emission Colors: Investigation into the Influences of Chemical Structure and Morphology
关键字：chemical structures，conjugated polymers，films，fluorescence，morphology
A series of PPV fi lms with different fl uorescent emission colors are prepared using a facile approach. Modifi ed from the conventional Wessling route, the labile sulfonium groups in the polymer precursor (pre-PPV) are partly substituted to various degrees by relatively stable methoxy groups, followed by a regular thermal elimination step to obtain PPV. Different chemical structures among these...

Synthesis and Crystal Structures of Two Heterobinuclear Nickel Polymers [NiNaL(dca)]n and [NiNaL(dca)]2n·(CH3COOCH3)n·(H2O)n
关键字：chainlike structure, dicyandiamide, heterobinuclear polymer
At the same condition, utilizing the different of base, the authors
constructed two wholly different compounds, 1 and 2. Compounds
1 and 2 are one-dimensional (1D) chainlike, while the coordination
mode of dicyandiamide is different in both complexes. In 1, the
dicyandiamide is μ1,5-dca bridged coordination mode; in 2, that is
μ1,3-dca bridged coordination mode. Two new heterobinuclear nick...

Biosens. Bioelectron., Glucose sensors based on electro-deposition of molecularly imprinted polymeric micelles: a novel strategy for MIP sensors
关键字：Glucose sensor, amphiphilic polymer
A voltammetric glucose sensor was prepared from novel molecularly imprinted polymeric micelles
(MIPMs) through direct electrodeposition. The MIPMs, which were photo-crosslinkable and nano-scaled with high specific surface area, were prepared via macromolecule self-assembly of an amphiphilic photo-crosslinkable copolymer, combined with a molecular imprinting technique using glucose as the template...
