Thermally robust: triarylsulfonium ionic liquids stable in air for 90 days at 300 °C

Select triarylsulfonium salts constitute ionic liquids with outstanding long-term, high-temperature aerobic stability (no mass loss in 90 days at 300 °C in air), making them among the most thermally stable organic materials known. A detailed analysis of their thermophysical properties reveals that lowering melting points in these salts by increasing ion size or lowering ion symmetry cannot be assumed, but remains an iterative process.

ONIUM BORATE SALT, ACID GENERATOR, CURABLE RESIN COMPOSITION AND CURED BODY PREPARED THEREWITH

PROBLEM TO BE SOLVED: To provide an onium borate salt and the like having cationic polymerizing performance and crosslinking reacting performance. SOLUTION: An onium borate salt contains onium borate salt (OB1) represented by general formula (1) and onium borate salt (OB2) represented by general formula (2), where the content of (OB2) in (OB1) and (OB2) is 0.01-4 wt.% [(R1)n+1-E]+ [(R2)bB(Ar)4-b]- (1), [(R1)n+1-E]+ [(OH)(R2)bB(Ar)3-b]- (2) [in formulae (1) and (2), E represents an n-valence element of Group VIA to Group VIIA (CAS notation) and n is an integer of 1 or 2; R1 is an organic group bonded to E; R2 is an organic group bonded to B (boron) and b is an integer of 1 to 3; and Ar represents a substituted phenyl group and b is an integer of 1 to 3].

PHOTOACID GENERATOR AND RESIN COMPOSITION FOR PHOTOLITHOGRAPHY

PROBLEM TO BE SOLVED: To provide a nonionic photoacid generator having high photosensitivity to i-line, excellent heat-resistant stability, high compatibility with a hydrophobic material, and excellent solubility in a resist solvent. SOLUTION: A nonionic photoacid generator (A) represented by formula (1) below is provided. In the formula (1), R1 and R2 represent a hydrocarbon group having 1 to 18 carbon atoms, which may have a substituent (where a part of or all of hydrogen atoms may be replaced by fluorine atoms), and R1 and R2 may be identical or different from each other; and Y is a group represented by formula (2).
