| 제목 | Electrochemical Deposition of (Pyrrole-1-yl)-Substituted Perylene Diimide for Electrochromism and Photoluminescence |
| 초록 | A diimide (PDI-2Py) was synthesized by imidization of 3-pyrrole-1-yl-propylamine and 1,6,7,12-tetrakis(4-tert-butylphenoxy)perylene-3,4,9,10-tetracarboxylic acid dianhydride. In the films prepared by electrodeposition of PDI-2Py between 0 and 1.2 V (vs. Ag/Ag+) in a potentiodynamic mode, the electroactivity of PDI moiety in a monomer-free solution increased with the number of the electrodeposition cycles. Considering that PDI without pyrrole moiety can not be electrodeposited under the similar conditions and that the pyrrole moiety can be electropolymerized at ca. 1.0 V vs. Ag/Ag+, we can deduce that PDI-2Py was electropolymerized to form the corresponding polymer [P(PDI-2Py)]. In the electrochromic study, P(PDI-2Py) turned red (λmax: 573 nm) and emerald (λmax: 788 nm) at 0 and -0.8 V (vs. Ag/Ag+), respectively. P(PDI-2Py) emitted red color (λmax: 629 nm) upon photoexcitation at 573 nm. |
