(57) Summary: Prepared from a group of fluorophores having the following general formula--generally including quinazolinones (quinazolones), benzimidazoles, benzothiazoles, benzoxazoles, quinolines, indolines and phenanthridines. , A novel fluorescent precipitable substrate: [Wherein the -C 1 = C 2 -carbon atom is further linked to complete a first 5 day or 6 chang aromatic ring which may contain at least one heteroatom N, O or S, -C 4 = N = C 3 - carbon atoms further includes at least one heterologous chamber atom is between C 3 and C 4, and further comprising at least one heteroatom N, O or S A second 5- or 6-membered aromatic ring which can be linked to complete, the first and second aromatic rings including at least C 2 from the first aromatic ring and C 3 from the second aromatic ring. It may be linked by a 5- or 6-membered bridged ring, which may be saturated or unsaturated and may contain heteroatoms N, O or S, Each of the two aromatic rings contains at least one heteroatom N, O or S It may be fused to at least one other aromatic ring which is possible, and each aromatic ring is further such that any hydrogen on the aromatic carbon is halogen, nitro, cyano, aryl, lower alkyl (carbon atom 1- 4), perfluoroalkyl (1-4 carbon atoms), or alkoxy (1-4 carbon atoms), or any combination thereof, which may be modified by substitution. ; X n is covalently bonded at C 1 to the oxygen -O-]. |
