Donor acceptor type neutral state green polymer bearing pyrrole as the donor unit

Neutral‐State Green Conjugated Polymers from Pyrrole Bis‐Substituted Benzothiadiazole and Benzoselenadiazole for Electrochromic Devices

“…[8][9][10][11] Although many pyrrole containing conjugated polymers are used to construct electrochromic devices, few of them satisfied the green color in neutral states which is significant for RGB devices. [12,13] Recently, quinoxaline and benzotriazole inserted pyrrole derivatives were synthesized and characterized in terms of their electrochromic properties. [14] However, new donor-acceptordonor type materials with pyrrole moiety should show up in the field to enhance device properties.…”

Syntheses and optoelectronic properties of quinoxaline polymers: The effect of donor unit

“…2). As other quinoxaline derivative polymers,11, 13, 17 both PTBPTQ and PTBPETQ have n‐doping properties at ambient conditions, which is a rare property in electrochromic polymers (Fig. 3).…”

Influence of hydrogen bonding on electrochromic properties of conducting polymers

“…Based on previous parallel studies, shifting from 9.4 to 10.6 is due to the intramolecular hydrogen bonding since H-bonded species mostly shift to a lower field [19,20]. Comparing the chemical shifts of the BImB in DMSO-d 6 and CDCl 3 , it is seen that the free acidic proton shifts from 9.4 ppm (in CDCl 3 ) to 13.3 ppm (in DMSO-d 6 ). This significant low field shift is due to the formation of intermolecular H-bonds with DMSO-d 6 [21].…”

“…Conjugated polymers are taken into account as inspiring materials over the past three decades since they have enormous advantages over their inorganic counterparts in use of optoelectronic devices such as light emitting diodes, field effect transistors, organic solar cells, and electrochromic devices [1][2][3][4][5][6]. One of the most important advantages is their ease of fine-tuning ability via structural modification to get desirable polymers with improved electrochemical properties [7,8].…”
