Title:

VANADIUM PHTHALOCYANINE COMPOUNDS AND NEAR-INFRARED ABSORPTION FILTER USING THE SAME

Document Type and Number:

WIPO Patent Application WO/2010/076968

Kind Code:

A3

Abstract:

Disclosed are novel vanadium phthalocyanine compounds with low absorption efficiency in the visible light domain and high absorption efficiency in the near-infrared light domain, and a near-infrared absorption filter using the same. The near-infrared absorption vanadium phthalocyanine compounds have chemical formula 1. In the chemical formula 1: A2, A3, A6, A7, A10, A11, A14, and A15 individually represent OR1, SR2, or a halogen atom, wherein at least four thereof represent OR1; A1, A4, A5, A8, A9, A12, A13, and A16 individually represent OR1, SR2, NR3R4,or a halogen atom, wherein at least one thereof represents NR3R4 andat least four thereof represent OR1; R1, R2, R3, and R4 individually represent an alkyl group with 1-10 carbons, an aryl group with 6-10 carbons, or an aralkyl group with 7-15 carbons.
