연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

Phthalocyanine (Pc), which has an electron-rich, aromatic structure, exhibits excellent optical properties as well as thermal and chemical stability. Numerous Pc derivatives, based on highly conjugated ring systems, have been proposed to facilitate efficient energy or electron transfer. They have be...

제안 방법

  • UV-Vis absorption spectra and photoluminescence spectra were obtained using a Shimadzu UV-1800 spectrophotometer and a Perkin-Elmer LS-45 spectrofluorometer, respectively. In addition, self-assembly monolayer (SAM) was formed on the ITO glass, and physical properties were evaluated. The SAM-covered ITO glass was analyzed using scanning electron microscopy (JEOL JSM-6700F) and XPS (AXIS SUPRA, Kratos Analytical Ltd.
  • In this study, we synthesized two Pc-TEOS derivatives having a siloxane end-group linked by the different alkyl chain spacers. The synthesis of Pc-C3-TEOS and Pc-C14- TEOS with high purity was confirmed by 1H-NMR and MALDI-mass measurement.
  • The 1H-NMR spectra was recorded on Inova Tech at 500 MHz using CDCl3 as solvent and MALDI-TOF mass spectrometry were performed at the Korea Basic Science Institute in Ochang (Korea). UV-Vis absorption spectra and photoluminescence spectra were obtained using a Shimadzu UV-1800 spectrophotometer and a Perkin-Elmer LS-45 spectrofluorometer, respectively.
  • In addition, self-assembly monolayer (SAM) was formed on the ITO glass, and physical properties were evaluated. The SAM-covered ITO glass was analyzed using scanning electron microscopy (JEOL JSM-6700F) and XPS (AXIS SUPRA, Kratos Analytical Ltd.). Cyclic Voltammetry (CV) was measured to examine the electrochemical properties of the prepared SAM using SP-150 (Bio-Logic SAS).
  • The Pc SAMs have been effective in electrochemical sensing applications [22−24]. The cyclic voltammetry (CV) was measured to investigate the electrochemical properties of PcC3-TEOS and Pc-C14-TEOS coated ITO electrodes. For CV measurements, Pc-coated ITO glass, Pt wire, and Ag wire were used as the working, counter, and reference electrodes, respectively.
