The present invention relates to a light-curing, reactive, pressure-sensitive adhesive film of adhesive. With the film of adhesive of the invention, structural bond strengths can be achieved. The film of adhesive comprises (a) at least one reactive monomer or reactive resin, (b) an initiator, (c) a photoredox catalyst, (d) a polymer of monomers comprising N-vinyl compounds and (e) a film-forming polymer.

A spacer, a method for manufacturing the spacer, and a display device are provided. The method includes: a step S10 of reacting a resin compound and a pyridine compound to generate an intermediate, a step S20 of reacting the intermediate and a metal ligand by a coordination reaction to obtain a coordination structure, and a step S30 of mixing the coordination structure, a monomer, a solvent, a starting agent, and an additive to prepare the spacer.

Exemplary methods, catalysts, catalyst compositions and systems are provided to activate a latent ruthenium olefin metathesis catalyst using a deep red to near infrared light (e.g., 600-800 nm) in conjunction with an osmium (II) photocatalyst that is directly excited to its triplet state via spin-forbidden excitation. An excited state single electron reduction of a latent solvent coordinated, cationic pre-catalyst is proposed as the operating mechanism for activation and photocontrol, as probed via in situ LED NMR kinetic studies and cyclic voltammetry. Excellent levels of spatiotemporal control can be found under light irradiation. NIR olefin metathesis exhibits improved light penetration through barriers over lower wavelengths of light, a control element that was deployed to mold dicyclopentadiene via Ring Opening Metathesis Polymerization (ROMP).
