본 연구에서는 새로운 종류의 공액 고분자 3-(5-(5,6-bis(octyloxy)-7-(thiophen-2-yl)benzo[c][1,2,5]thiadiazol-4-yl)thiophen-2-yl)-10-(4-(octyloxy)phenyl)-10H-phenothiazine (P1)과 3-(5-(5,6-bis(octyloxy)-7-(thiophen-2-yl)benzo[c][1,2,5]thiadiazol-4-yl)thiophen-2-yl)-10-(4-((2-ethylhexyl)oxy)phenyl)-10H-phenothiazine (P2)를 스즈키 커플링 반응으로 합성하여 유기박막 태양전지로의 특성을 확인하였다. Push-pull 구조 고분자의 전자주개 물질로 phenothiazine 유도체를, 전자받개 물질로 benzothiadiazole 유도체를 사용하였다. 전자를 풍부하게 하고, 용해성을 향상시키기 위하여 phenothiazine의 질소 원자에 알콕시 사슬이 도입된 방향족 고리를 치환하여 2종의 고분자(P1, P2)를 합성하였다. P1, P2의 분자량은 각각 4,911, 5,294이었고, Td는 각각 321.9, 323.7 ℃로 이로부터 열 안정성이 우수함을 확인하였으며, 최대흡수파장은 549, 566 nm이었다. 소자를 제작하여 박막태양전지의 특성을 측정한 결과, P1과 P2의 효율은 각각 0.96, 0.90%이었다.

In this study, a new series of conjugated polymer 3-(5-(5,6-bis(octyloxy)-7-(thiophen-2-yl)benzo[c][1,2,5]thiadiazol-4-yl)thiophen-2-yl)-10-(4-(octyloxy)phenyl)-10H-phenothiazine (P1) and 3-(5-(5,6-bis(octyloxy)-7-(thiophen-2-yl)benzo[c][1,2,5]thiadiazol-4-yl)thiophen-2-yl)-10-(4-((2-ethylhexyl)oxy)phenyl)-10H-phenothiazine (P2) were synthesised and organic photovoltaics (OPVs) properties were characterized. The push-pull structure polymer consisted of phenothiazine derivative as an electron donor and benzothiadiazole derivative as an electron acceptor. The aliphatic chain substituted aromatic ring was substituted at the position of N in phenothiazine for the electron-rich and improved solubility. Excellent thermal stabilities of P1 and P2 were confirmed by measured Td values as 321.9 and 323.7 ℃, respectively and the degrees of polymerization were 4,911 (P1) and 5,294 (P2). The maximum absorption wavelength of P1 and P2 were 549 and 566 nm, respectively. The device was fabricated and the OPVs property was measured. As a result, the power efficiency of conversion for P1 and P2 were 0.96 and 0.90%, respectively.
