LIGHT-DEGRADABLE MATERIAL, SUBSTRATE AND METHOD FOR PATTERNING SAME

WIPO Patent Application WO/2014/058061

A1

[Problem] To provide a novel material which allows finer patterning and is applicable to the control of adsorption/adhesion of various cell species, proteins, viruses, etc. without restricting the light source. [Solution] A light-degradable material comprising a moiety that is capable of bonding to the surface of a substrate via a siloxane bond, and structural unit(s) represented by formula (2-a) and/or formula (2-b). In formulae (2-a) and (2-b); R2 to R4 represent each a saturated straight-chain alkyl group; X represents a hydrogen atom or an alkyl group; Z represents a carbanion or a sulfo anion; Q represents an ester bond group, a phosphate diester bond group, an amide bond group, an alkylene group, a phenylene group or a combination of these divalent groups; m1 represents an integer of 1-200; and n represents an integer of 1-10.
