Heat capacity and phonon dispersion in polyselenophene in relation to the spectra of oligoselenophenes

Highly stable hybrid selenophene-3,4-ethylenedioxythiophene as electrically conducting and electrochromic polymers

“…[3][4][5][6][7][8][9][10] Great progress in polyselenophenes has been made over the last several years; in addition to the parent polyselenophene, [11][12][13][14][15][16] several typical polyselenophenes with excellent properties have been recently reported for optoelectronic applications (their structures are shown in Scheme 1). These include poly(3,4-ethylenedioxyselenophene), 3 poly(3,4-ethylenedithioselenophene), 4 poly(n-hexyl-3,4-ethylenedioxyselenophene), 5 poly(alkyl-3,4-ethylenedioxyselenophenes), 6 thieno-/selenolo-fused polyselenophene, 7 polyselenopheno [3,4-b]selenophene, 8 poly(3,4-propylenedioxyselenophene), 17 poly(3-alkylselenophene), 18 etc., along with several selenophene-based hybrid polymers, 7,8,[19][20][21][22][23][24] leading to the availability of promising polyselenophene materials. Most recently, our group investigated the thermoelectric performances of different types of polyselenophene; we found that polyselenophene exhibits a very high Seebeck coefficient (>180 V K À1 ) and holds promise for thermoelectrics.…”

Effect of electrolytes on the electropolymerization and optoelectronic properties of poly(3-methylselenophene)

“…1,2 In this context, great strides in polyselenophene research have been achieved over the last several years. 1,2 Besides parent polyselenophene, [3][4][5][6][7][8] several typical polyselenophenes with excellent performances have recently been reported, such as poly(3,4-ethylenedioxyselenophene), 9 and its analogues and derivatives, [10][11][12][13] thieno-/selenolo-fused polyselenophene, 14 polyselenopheno [3,4-b]selenophene, 15 poly(3-alkylselenophene), 16 etc., along with several selenophene-based hybrid polymers, [17][18][19][20][21][22][23][24] leading to the availability of promising polyselenophene materials. Our group has systematically investigated the effect of different monomeric precursors and electrolyte systems on the electropolymerization and properties of polyselenophene, and also designed a family of selenophene-EDOT conjugated systems and explored their optoelectronic properties.…”
