Despite high co-planarity and strong polar bicyclic lactam structure, TBPD has been less explored compared to other bis-lactam structures, mainly due to its low yield in its synthesis via lactone-to-lactam conversion. By using a higher yield synthesizing methodology of TBPD, systematic studies were performed to figure out the correlations between thin-film microstructures and charge carrier mobilities of four newly synthesized TBPD-based polymers. We could report further improved the electrical characteristics of fabricated organic field-effect transistors with optimal solution-processing method (high boilingpoint solvent, solution-shearing process and optimized thermal treatment). Our investigation is expected to promote future research and development associated with the TBPD unit.

목적: 최근 알레르기질환의 급증과 함께 아토피피부염 환자도 증가하고 있다. 대한소아알레르기 및 호흡기학회에서 2000년도에 전국의 초등, 중학생 43,045명을 대상으로 설문조사한 결과에 의하면 초등학생의 24,9%, 중학생의 12.8%가 아토피피부염을 진단받은 것으로 조사되었다. 저자들은 아토피피부염의 빈도와 호발 연령 대, 원인 항원에 있어 10년 전 조사 결과와 비교하여 변화를 알아보고자 본 연구를 시행하였다. 방법: 2001년 8월부터 2002년 Purpose: The prevalence of atopic dermatitis has been increased in the last decade. The purpose of this study is to compare the prevalence, and the etiologic allergens of atopic dermatitis in children between the year of 1992 and 2002. Methods: The study

The development of top-performing π-conjugated polymers that can provide good solubility and processability in non-toxic solvents is imperative for the advancement of organic electronic devices. Based on molecular structural control, especially controlling irregularity and electron-acceptor of polymer backbone, we have developed non-chlorinated and eco-friendly solvent processable polymer semiconductors and high-performing organic field-effect transistors (OFETs). The remarkable charge mobilities were obtained from various eco-friendly solvent-processed OFETs compared to chlorinated solvent-processed ones. This study will provide guidelines for developing high performance semiconductors for their use in the manufacturing of green and sustainable plastic transistors.
