Fabrication of Microporous Films Utilizing Amphiphilic Block Copolymers and Their Use as Templates in Poly(aniline) Preparation

Nanoporous Membranes of Hydrogen‐bridged Smectic Networks with Nanometer Transverse Pore Dimensions

“…[21,22] A bottom-up approach, using self-organization by the controlled microphase separation of block copolymers and the subsequent removal of one of the blocks, provides a variety of pore shapes and sizes depending on the molecular weight and types of micellar phases. [23][24][25] For smaller dimensions supramolecular dendritic structures can self-assemble into pores with a well-controlled inner chemical nature. [26,27] Bottom-up methods that are especially appealing are based on the self-organization of liquid crystals and their polymers because they decrease the pore sizes down to the order of molecular length scales, for example, around 1 nm and below, while the assemblies themselves can have much larger dimensions.…”

Synthesis and Characterization of Poly(3-hexylthiophene)-b-Polystyrene for Photovoltaic Application

“…Polystyrene with tert-butyl ester as an end functional group (1) was synthesized by ATRP using CuBr/CuBr 2 /PMDETA system as reported elsewhere [25]. 1 H NMR signals for the initiating end group (CH 3 CH-, and -C(CH 3 ) 3 ) for PS resonated at 0.9 and 1.35 ppm in CDCl 3 , respectively, and the degree of polymerization (DP) was determined to be 25 based on the relative intensity of the former signal to aromatic protons.…”

Synthesis of Diblock Copolymer Consisting of Poly(4-butyltriphenylamine) and Morphological Control in Photovoltaic Application

“…Taking its good compatibility with PCBM into account, PS was selected as the other segment. The PS terminal modifier (PS-Br) was synthesized by ATRP initiated from 1 using CuBr/CuBr 2 /PEDMTA catalytic system as reported elsewhere [42]. Two kinds of PS-Br with different number average molecular weights (M n = 2,300 and 4,300) were prepared.…”
