Synthesis and Physical Characterization of β-Alkyl Oligoselenophenes
摘要:
alpha-Conjugated oligoselenophenes are characterized by very low solubility in organic solvents. Their higher solubility may be achieved by introducing alkyl side chains into the -positions of selenophene moieties. For the first time, ,-dihexyl sexiselenophene is synthesized according to the conventional approach. Physical and electrochemical studies of ,-dialkyl oligomers are analyzed and compared with corresponding thienyl oligomers.

marked effect on their binding affinities. The compound bis(2‐fluoro‐4‐hydroxyphenyl)selenophene (2 f) has the highest relative binding affinity (RBA) of 24.3 for ERβ. In transcription assays, most selenophenes were found to exhibit partial to full agonist activity for both ER subtypes, with compounds bis(2‐methyl‐4‐hydroxyphenyl)selenophene (2 b), bis(4‐fluoro‐3‐hydroxyphenyl)3‐bromoselenophene (6 f),
Rational design and optimization of selenophenes with basic side chains as novel potent selective estrogen receptor modulators (SERMs) for breast cancer therapy
Selenophenes with basic side chains showed excellent antagonist activity for ERs and increased antiproliferative activity than that of 4OHT in MCF-7 cells.

(selenophene) ring fragmentation followed by azide–alkyne cycloaddition, were investigated as a basis for nonlinear optical (NLO) materials capable of second harmonic generation (SHG). The structure–property relationship was mapped by systematic variation of the molecular scaffold, viz., elongation of the alkyl groups, isomerizations of both the double bond as well as the triazole moiety, sulfur oxidations
