VANADYL PHTHALOCYANINE COMPOUNDS AND NEAR-INFRARED ABSORPTION FILTERS USING SAME

摘要

Disclosed are novel vanadyl phthalocyanine compounds and near infrared- absorbing filters which utilize the same, and which demonstrate low contrast light absorption in the visible region and longer wavelength absorption in the near-infrared region (in particular, wavelengths between 950 and 1100 nm), indicating high absorption efficiency. The phthalocyanine compounds are represented by Claim 1 and chemical Formula 1.
