This invention provides dye phosphoramidites, particularly phosphoramidites of substituted cyclic bridged cyanine and related dyes, of the general formula: In this formula, each dotted line represents carbon atoms necessary to form a fused substituted or unsubstituted aromatic ring; m is an integer from 1 to 18; Y and Z are independently selected from the group consisting of S, O, N, CH<SUB>2 </SUB>and C(CH<SUB>3</SUB>)<SUB>2</SUB>; R<SUB>1 </SUB>is an alkyl; (PAM) is a phosphoramidite group; X<SUP>{circle around (-)}</SUP> is a negative ion; and Q is L-W, wherein L is a conjugated cyclic moiety and W is OR<SUB>2</SUB>, wherein R<SUB>2 </SUB>is a second alkyl. Methods of making and using the dye phosphoramidites are also provided.
