“…[16][17][18][19][20][21][22][23] In addition, al arge number of TPA-based polymers exhibit electrochromic behaviord uring redoxp rocesses that have potential applications in ECDs. [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] To improve the charge carriert ransport properties and structural stabilities of polymerc hains, somet hiophene derivatives, such as 2,2'-bithiophene and 3,4-ethylenedioxythiophene (EDOT), have been incorporated within the polymer backbonea s" bridge" linkages.

“…As eries of monomers that consist of aT PA core substituted by thiophene derivatives was synthesized recently,a nd the resulting polymers possess good electrochemical stabilitya nd variouse lectrochromic properties. [31][32][33][34][35][36] One of these reported monomers is tris [4-(3,4-ethylenedioxythiophene)phenyl]amine (TEPA), which was synthesized by the Stille cross-coupling reaction. [31,37] Chahma et al [37] and Idzik et al [38] prepared poly-{tris [4-(3,4-ethylenedioxythiophene)phenyl]amine} (PTEPA) films by electrochemical polymerization andf ound that they have significant electroactivity and reasonable redox stability,a lthought hese films are insoluble in all common solvents.…”

“…Among these reported conjugated polymers, many polymers based on triphenylamine (TPA), which have ultrafast electron‐transfer rate constants and good hole‐transporting abilities, have been studied intensively as electrode materials for organic batteries and SCs . In addition, a large number of TPA‐based polymers exhibit electrochromic behavior during redox processes that have potential applications in ECDs . To improve the charge carrier transport properties and structural stabilities of polymer chains, some thiophene derivatives, such as 2,2′‐bithiophene and 3,4‐ethylenedioxythiophene (EDOT), have been incorporated within the polymer backbone as “bridge” linkages.…”

Multichromic Polymers Containing Alternating Bi(3-Methoxythiophene) and Triphenylamine Based Units with Para-Protective Substituents

“…The invention of conductive acetylene opens a new chapter in the basic and application research of conducting polymers (CP) [ 1 ]. Thereafter, they became the crucial materials in practical applications such as field effect transistors [ 2 ], photovoltaic [ 3 ], chemical sensors [ 4 ], thermal emission detectors, electrochromic materials [ 5 ], etc. Electrochromism was defined as the phenomenon that some materials displayed reversible optical change in absorption or transmittance when a doping–dedoping process was performed [ 6 ].…”
