Provided are compounds comprising two DNA supramolecular binding molecules covalently joined by a linker group. Also provided are multisignal labeling reagents comprising (i) an oligomer of nucleotides or nucleotide analogs; (ii) a DNA supramolecular binding molecule noncovalently bound to the oligomer; and (iii) a first reactive group or a first partner of a first binding pair covalently bound to the oligomer. Additionally provided are methods of producing multisignal labeling reagents.

A photoactivatable caged compound (TPE-C) with AIE characteristics is designed and synthesized. TPE-C is non-emissive either in solution or in aggregated state, but its luminescence can be induced to emit strong cyan emission in aggregated state by UV irradiation. Such property enables TPE-C to be applied in photo-patterning and anti-counterfeiting related areas.

A colored composition is provided having higher heat resistance as compared with a conventional colored composition using triarylmethane derivative.

The present invention relates to a compound represented by the following general formula (1), and a polymer having a monomer unit derived from the compound, and the like.

##STR00001##

(wherein R.sub.1 to R.sub.4 each independently represent an alkyl group or the like; R.sub.5 to R.sub.7 each independently represent a hydrogen atom or a methyl group; n pieces of R.sub.8 each independently represent a halogen atom, an alkyl group, an aryl group, a hydroxy group, a nitro group, a sulfo group, an alkoxy group, or the like; and n represents an integer of 0 to 4. A.sub.1 represents an alkylene group, or the like; A.sub.2 represents NH or O. An.sup. represents an anion containing an aryl group having an electron-withdrawing substituent, a sulfonyl group having an electron-withdrawing substituent, or a halogenated alkyl group.)
