Synthesis and electrochemical properties of new star-shaped thiophene oligomers and their polymers

Synthesis and Electrochemical Properties of Novel 1,3,5-Tris(oligothienyl)benzenes: A New Generation of 3D Reticulating Agents

“…The expected products 2 are isolated in good yields by column chromatography using dichloromethane as the eluent. According to our previous work, [16] we have modified the ketolization±dehy-dratation reaction such that the major products are the 1,3,5-tris(5-oligothienyl)benzene derivatives 3. This is achieved using five equivalents of TCS instead of one, and increasing the reaction time to 18 h from the 2±4 h described in the original paper.…”

Enhanced Conductivity of Polyaniline by Conjugated Crosslinking

“…[9] Expecting that the introduction of conjugated crosslinkers between the conjugated conductive macromolecules could represent an approach for the design of (semi)conducting polymers with increased charge-transport characteristics. [10,11] Here, we design and synthesize a new network conductive copolymer via chemical oxidation copolymerization of aniline (An) and p-phenylenediamine (PPDA) with triphenylamine (TPA) as crosslinker.…”

Electrochemical and spectral properties of meta-linked 1,3,5-tris(aryl)benzenes and 2,4,6-tris(aryl)-1-phenoles, and their polymers

“…It has previously been reported in the literature, that branched oligothiophenes and oligothienylbenzenes act as monomers in cross-linked semiconducting polymers [3][4][5], and as components of conjugated dendrimers [6][7][8][9][10]. This type of polymers can be characterized by a three-dimensional structure, which is on the sake of their conductivity [11].…”
