Novel linkers for linking a donor dye to an acceptor dye in an energy transfer fluorescent dye are provided. These linkers faciliate the efficient transfer of energy between a donor and acceptor dye in an energy transfer dye. One of these linkers for linking a donor dye to an acceptor dye in an energy transfer fluorescent dye has the general structure R
21
Z
1
C(O)R
22
R
28
where R
21
is a C
1-5
alkyl attached to the donor dye, C(O) is a carbonyl group, Z
1
is either NH, sulfur or oxygen, R
22
is a substituent which includes an alkene, diene, alkyne, a five and six membered ring having at least one unsaturated bond or a fused ring structure which is attached to the carbonyl carbon, and R
28
includes a functional group which attaches the linker to the acceptor dye.
