    摘要: Fluorescent chromophores nicknamed BOPHY are provided. The chromophores may be readily synthesized in two steps from readily available reagents via the coupling of a pyrrole aldehyde or ketone with hydrazine, followed by reaction with BF3. The resultant symmetric and dimeric tetracycle is comprised of two BF2 units in six-member chelate rings, appended by pyrrole units on the periphery. The quantum yield of fluorescence for the unmodified compound and the tetramethyl variant are near unity, with values 95 and 92% respectively in CH2Cl2.

    摘要: Disclosed is a silver halide photographic material which comprises at least one methine dye represented by the following formula (I): wherein Y represents a furan ring or a pyrrole ring, and Y may further be condensed with other 5- or 6-membered carbocyclic ring or heterocyclic ring, or may have a substituent; the bond between two carbon atoms in which Y is condensed may be a single bond or a double bond; Z represents an atomic group necessary to form a 5- or 6-membered nitrogen-containing heterocyclic ring, and Z may further be condensed with other 5- or 6-membered carbocyclic ring or heterocyclic ring; R represents a substituted or unsubstituted alkyl group, aryl group, or heterocyclic group; D represents a group necessary to form a methine dye; L1 and L2 each represents a methine group; p represents 0 or 1; M represents a counter ion; and m represents a number of 0 or higher necessary to neutralize the charge in the molecule.
