Abstract: External energy is fed to N-[3-{3,5-bis{3,5-bis[3,5-bis(4-mercaptobenzylthio)benzylthio]benzylthio}benzyloxy}-propionyl-4-nitro-1-naphthylamine (18a) being a molecule capable of photosensitization as an intermediate excitation medium, fixed on support (12) of a metal, so as to photosensitized molecule of excited triplet state (18b), thereby inducing an excited triplet energy transfer from this photosensitized molecule to first molecule (28a) having a residue capable of bonding. The first molecule (28b) having thus been excited by the excited triplet energy transfer is bonded with second molecule (30) having a residue capable of bonding which is a bonding object to be bonded with the first molecule.

Abstract: Abstract: A probe comprising support (12) of a gold wire and, fixed thereon, intermediate excited medium (18a) having been excited to an excited triplet state by supply of external energy thereto, wherein transfer of excited triplet energy is effected from the intermediate excited medium toward a first molecule having a residue with bonding capability. The first molecule having thus been excited by the transfer of excited triplet energy is bonded with a second molecule having a residue with bonding capability as a bonding target to be bonded with the first molecule.

Abstract: The present invention is directed to novel thioether dendritic molecules which respond immediately by emission of light when stimulated with light or electric energy.
