An onium salt and a composition having high sensitivity and excellent pattern characteristics such as LWR, which is preferably used for a resist composition for a lithography process using two active energy rays of a first active energy ray such as an electron beam or an extreme ultraviolet and a second active energy ray such as UV.
Acidic proton modulation of a stilbene-based zwitterionic sulfonic acid in the crystalline state was studied using three amines with different pKa values. The three organic crystal structures prepared from the intermolecular interactions of the acid with the amines and water were solved by single-crystal X-ray crystallography. These crystals included an ammonium salt and two hydrate crystals. Furthermore, the three generated crystals could mimic three distinct biological systems: a water/proton blockade, a protonated water array, and a one-dimensional water channel.

Nitroxides having an alpha-carbon atom with a destabilizing moiety are effective control agents for emulsion and water-based polymerizations, including the formation of block copolymers from a wide range of monomers. The nitroxide radicals may be used as a free radical or as an adduct with a residue from the initiator. The emulsions have living characteristics, including the re-initiation of polymer chains. Also, a seeded process for emulsions, which includes the step-wise addition of monomer is disclosed, providing access to a wide range of initiator types.
To provide a multinuclear complex including at least one ligand L satisfying the following requirements (i) r (ii) and (iii), and a plurality of metal atoms in a molecule:
(i) having a group having polymerizable reactive multiple bonds, and/or a ring-opening polymerizable ring,
(ii) having five or more coordination atoms bonding to the metal atoms, and
(iii) being soluble in a solvent.
