Title:

PYRAN DERIVATIVES AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/1999/040086

Kind Code:

A1

Abstract:

Pyran derivatives represented by any of chemical formulae (1) to (3). They are highly sensitive to visible light and highly luminescent and hence are useful in various applications in photochemical polymerization, organic electroluminescence, and dye lasers. In chemical formulae (1) to (3), R¿1? and R¿2? each independently represents hydrogen, alkyl, alkenyl, or aryl (the alkyl and aryl may be substituted); R¿3? represents cyano, carboxyl, a carboxylic ester group, amido, or a five- or six-membered heterocycle optionally forming a fused ring; and R¿4? represents hydrogen, halogeno, cyano, carbonyl, or a substituent derived from carbonyl, provided that R¿1? and/or R¿2? may form a cyclic structure in cooperation with the benzene ring bonded thereto.
